This book is just genericly OK until the end. And not the end of the major plot point, the end where one of the narrators finally deals with her brother's suicide. And I wish that had been a more major part of the story, because it's heartbreaking and an honest part of the story. The main plot, the one the narrators tell is a pretty basic Kind of the Land story and if you know mythology at all you're about three to four steps ahead of the narrators as far as that plot point goes, and that's a little annoying. It's the characters who tell the story that make it so enjoyable.
Not as strong as her debut novel, but I'd still say Healey is an author to keep an eye on.
