Review:
This review will include spoilers for the first book. You’ve been warned.
At the end of The Abyss Surrounds Us, Cas decided to stay with the Minnow and her crew. I wish I had written down her reason for doing so, since one of my problems with The Edge of the Abyss was that I couldn’t remember why she’d have wanted to stay when staying seemed to cause her nothing but grief.
At any rate, she stayed - I think because she wanted to get more evidence on the guy who was trading Reckoner pups to the pirates, and because she loved Swift so much? Except the latter reason turned out to be less than wonderful, because right after deciding to stay with the Minnow, Cas learned that Swift had personally been responsible for Durga’s death.
So that’s Cas’s emotional state for much of The Edge of the Abyss: upset at Swift for what she did, upset at herself for essentially turning traitor and staying with pirates, and perversely drawn to Santa Elena and whatever scraps of praise she was willing to give out. Bao is somewhere out in the ocean, and Cas mistakenly thinks he’s the only free Reckoner. He very much is not - the crew of the Minnow discover others, which they nickname Hellbeasts. Every last one of them was a Reckoner pup illegally obtained and improperly raised by pirates, and they’re complete destroying the ocean ecosystem. If life in the ocean is to be saved, the pirates, all of them, will somehow have to band together, admit their mistakes, and defeat the Hellbeasts.
