In The Mercy of Gods, the humans of the planet Anjiin became enslaved by the Carryx, and they didn't put up much of a fight. That's not surprising since the Carryx have been conquering other races for millennia, and their society is built on using conquered races as useful tools. If a race turns out not to be useful to the Carryx, then they simply eliminate them. Former research assistant, Daffyd Alkhor, now finds himself the leader of the human captives, but a role he achieved because he accepted captivity, to the dismay of many of the remaining humans. By betraying a group of human conspirators to the Carryx, Daffyd earned favor and established his leadership position; however, that came at a price since he alienated himself from the other captives in the process. He must now find a way to ensure that the humans remain useful to the Carryx, even though he is pretty much hated by all of them.

This series has really changed over the years and the original emphasis on Kaylin investigating crimes in a fantasy world, which usually ended with saving that world, has shifted to simply dealing with the world ending crisis. So her day job as a Hawk is mentioned mostly in regards to her absences, and mentions of the fief lord Nightshade, and her complicated feelings about him, see even fewer words than the Hawks. Until now, because Cast in Blood resurrects that story line when assassins attack Nightshade and the Lady of the Barrani with some kind of magical poison that might be a kind of Shadow. I’m remember the question at the end of book two. Will she be Erenne?

All four remaining Dreadgods have been awakened and are now rampaging across Cradle, threatening all inhabitants of the planet. As usual, it is up to the Monarchs to step up and offer protection to their citizens until the Dreadgods are once again slumbering. Unfortunately for everyone, Lindon now knows the Monarch's dirty little secret and he has concluded that the only long term solution to the Dreadgod problem is for the Monarchs to be gone from Cradle. With Eithan gone, Lindon is without his strongest ally, so how can he possibly hope to stand against both the Dreadgods and the Monarchs? Certainly not alone. But his remaining allies are not strong enough to fight Dreadgods or Monarchs, so they will need to grow in power as quickly as possible. If they do, then together they can stand as a team and do the impossible and forge a new future for Cradle.

The demons and their hordes of Possessed are winning the war against humanity. Only the great souls known as Battle Mages can stand against the demon fear and protect human armies, but too many potential Battle Mages are summoning the mad and violent black dragons, which must be killed thus leaving the Battle Mage brokenhearted. As humanity retreats and kings put politics above the common good, one sickly young man, son of a reviled Battle Mage who went insane along with his dragon, might be their only hope.

Koli Faceless, Ursala-from-Elsewhere, and Cup were a strange combination of traveling partners, but they each had their reasons for being part of the group heading towards London. Koli wanted to find the city of London, which was from the before-times when tech used to be plentiful, and he hoped to find some tech there to heal people like those in his former village so they could all have healthy children. Ursala had no real hope of finding London, but the signal they had picked up from Sword of Albion intrigued her enough to head towards it, and that meant heading in the same direction. Cup was more of a prisoner than a traveling partner, but Ursala did not trust the feral girl, and nothing Koli said could convince Ursala to grant Cup her freedom. And don't forget about Monono, the virtual girl that lived inside the DreamSleeve, the old tech that Koli had wakened thus causing him to be expelled from his village. An odd bunch trying to survive and do some good in a hostile world that was trying to kill them in all manner of different ways.

A young man saves a dragon egg and bonds to the unique dragon in this fantasy that’s half Dragon Riders of Pern and half Ender’s Game with undead. For centuries the noble born dragon riders have defended the world from the Scourge, giant insects that spread a Blight that raises the dead as ghouls to join their hordes. In the strict ordered society where Holt Cook was born, he knew he would die a cook, but still he dreamed of bonding with a dragon so he doesn’t hesitate to save a rejected egg when the opportunity arises. Of course, soon after the white dragon hatches, the dragonhold is overrun by the Scourge, leading Holt to discover that an ancient dragon with the ability to control minds is not only controlling the Scourge, but recruiting dragons to wipe out humanity. 

I thought we would be done with Sacred Valley after the events of the last book, but it turns out that those were just set up for this one. The gang is back in Sacred Valley, this time delving into the Labyrinth beneath, a dangerous place full of ancient powers and relics. The lure of the Soulsmith knowledge buried within is enough to convince Lindon and Eithan to take the risk, but the fact that Reigan Shen is already in there makes it a priority for everyone. Shen is there hoping to become immortal by turning himself into a Dreadgod and he must be stopped before it happens. At the same time, the Abidan are waging war in the heavens also trying to save Cradle, and the time finally comes for both series of events to finally come together in a big reveal.

The murder of an Imperial diplomat takes Din and Ana into the heart of the Empire's Apothetik division where dissecting Leviathans has led to mental corruption that's no less deadly than the physical corruption Leviathan's spread in their wake. Their case appears to be a simple locked room mystery, except the man seems to have robbed a bank vault containing Apothetik secrets after the time of death. Ana has no trouble figuring out the murder, but untangling the vault theft leads Ana and Din deeper and deeper into the secrets of the Apothetik order responsible for the alterations of Imperial servants that keeps the Empire safe. Local politicians, diplomats, and even the Apothetiks themselves have embraced forbidden practices, all in the name of the greater good. To save everyone in the city and the Empire's pipeline of alterations, Ana must make full use of her own alteration and in the process reveal what she really is to Din.

Way back in the first book of the Cradle series, Unsouled, Lindon's death was reversed by one of the Abidan and he was shown an event from his future - the destruction of his home, Sacred Valley, by a Dreadgod. Now here in the 9th book of the series, it is finally time for that foretelling to come to fruition. Advanced knowledge that this event was going to happen has been motivation for Lindon to advance through the Sacred Arts as fast as possible, but now he is out of time. He must return to his childhood home and stand against a Dreadgod if he wants to save his family, and his abilities are woefully inadequate for that task. Lucky for him he is not alone, but even the combined might and resources of all the main characters and the Akura clan are not enough to stop a Dreadgod, so their only choice is to evacuate as many as possible. Many will still die, so in a circumstance like this, what does victory even look like?

Every wet season the Leviathans emerge from the seabed and attempt to enter the Empire. Defending the people from the Leviathans is, in fact, why the Khanum started altering themselves using what they could extract from the Leviathans. The brilliant Khanum are long gone, except for the Emperor kept in stasis, but the bureaucracy and military live on thanks to those willing who volunteer for various alterations and serve their people despite the side effects, sterility, and shorter lifespans. Like most who sign up, Dinios Kol is doing it to support his family and he survived the difficult Engraving alteration which gives him perfect recall. But Din has a problem, he's Dyslexic in a world that doesn't know it exists, and can't find a position until Ana Dolabra takes him as her assistant. He's elated until he realizes she's insane. Ana is a brilliant investigator but also a total shut in who needs a talented Engraver to attend crime scenes and then regurgitate everything about it for her. It makes for an interesting symbiosis and their first murder case is a real doozy. An Engineer died when some kind of trees grew out of his chest in a wild burst twenty feet high. It looks like the contagion that springs up near a Leviathan's path but there should be other cases. Is it possible to poison someone with a contagion? As the wet season begins and the Leviathans challenge the sea wall, their case will take them to the Wall itself as a terrorist goes on a killing spree at the worst possible time. Who could possibly want to sabotage the Wall they all depend on?
