I found this to be an amazingly frustrating book. I wanted to smack BOTH the main characters, well before the end of the story.
It's not enough for an author to say that a character is acting like a selfish, spoiled idiot because he or she is a powerful non-human entity. The author owes it to the reader to make the character into someone who would live past childhood in a realistic setting. Baltic just wasn't such a character. His own parents would have strangled him, and no jury would have convicted them.
The viewpoint character, Tully, could only be explained if the reader assumes that she is on the point of a nervous breakdown, and that her repeated bizarre behavior is just a fringe effect from the fact that she's going quite mad. Calling an imporant, life-or-death meeting, and then focusing entirely on the canapes?
Her son should be adopted by the Addams family, so that he would have folks around who understand him.
I honestly found the comic relief throughout the story to be funny, but so poorly timed that it was jarring. I kept getting pulled out of what should have been an interesting story by Tully having sexual fantasies or magically manifesting bananas. No, really, she did that...bananas...
