It is hard to believe that this series has reached book eleven already, but here we are. Xavier has finally stepped down and is no longer King of the Vanguard Islands, so he heads off with Magnolia in search of Michael, who is missing. Michael is out there somewhere trying to find a home for his family after they managed to escape the islands in the last book. Since they took the last remaining airship with them, Kade Long, who has taken over as king, has inherited an impossible situation. The Knights of the Coral Castle are coming for them, and they have no remaining air power of any kind. His master plan is to send out Gran Jefe, of all people, along with a few Barracudas to bring back two helicopters from an ancient facility. X, Michael, Kade and Gran Jefe means there are four separate story lines going on at the same time in four different locations. Has this series finally lost its way or does it all come together into something coherent?

It is mostly the latter but this book ultimately only sets things up for book twelve, which is supposed to be the last one in the series. The Hell Divers series is like comfort food and the thought of it ending saddens me, but I also hope that the series finds a way to end on high note. This felt like it would make a decent trilogy when it started out, and while there have been times where I thought I would lose interest, here I am chomping at the bit for the finale. If you are a fan of the series don't hesitate to pick this one up, but be sure that you relish the time you get to spend with these characters, because the end is neigh, in more ways than one...

R. C. Bray narrates the audiobook version. Nuff' said, take my money.
