Early on in this series, Donut received a magical crown and of course she put it on before reading the description. The warning on the crown stated that the wearer would become a member of the Blood Sultanate and would not be able to leave the 9th floor of the dungeon without killing every other member of the Sultanate. This was a permanent liability as removing the crown does not negate the effect. She eventually replaced the crown, but that too was a mistake, because it allowed that same crown to be forcibly placed onto the head of fellow crawler Katia in a later book. At that point there was no way that both Donut and Katia could both reach the 10th floor, but it was a problem for another day. No longer. The 9th floor, known as Faction Wars, is finally here and it is one of the most deadly floors in the dungeon. Add on the Donut/Katia situation and there is no way that Carl makes it to the 10th floor without losing someone he loves.

The 7th floor of the dungeon was abruptly destroyed, so instead of the 7th floor this book takes place on the 8th, known as The Ghosts of Earth. Each team's leader must pick a location to start, and despite being well prepared for the Bahamas, Carl and Donut wind up in Cuba because Donut isn't exactly great at geography. Because no crawlers were eliminated on the aborted 7th floor, the AI has made the floor extra deadly in an attempt to dwindle down the number of crawlers before the 9th floor Faction Wars. This level requires the crawlers to collect monsters ala Pokemon in order to build out the decks they will use to combat other crawlers and NPCs in a real time version of Magic the Gathering. Of course, every part of this is done in a ridiculous over the top manner that culminates in an insane multiplayer card battle with everything at stake.

Viv is an orc babrarian, and after many years of adventuring she is ready to hang up her broadsword to pursue her dream of opening a coffee shop. Ever since she first smelled the gnomish drink she has been making plans and when her final job has her slaying a scavern queen she knows the time has come. According to an obscure legend the heart of a scavern queen will guarantee the success of its owner. Things seem to be going well until one of her old adventuring group comes seeking the heart and stirs up the local crime lord against Viv. Being a shop keeper is certainly more complicated and dangerous than Viv expected, but with help from her friends Legends and Lattes might be a great success.
