I feel very torn over this book. It had some really good elements, but it ended up feeling like a mishmash of too many genres. There was some suspense, some thriller, some romance, and then a totally inexplicable bit of supernatural that made no sense and caused the ending to be a hash for me.
I did find reading about another country's version of CPS very interesting. I thought it was odd that the father getting out of prison apparently meant that the child was supposed to go straight back to him. That's certainly not how it would have worked in any of the courts I practice in, and made me curious about Australia's CPS system.
Some of the characterization seemed kind of heavy-handed and the "blended family" dynamics were kind of forced. But, I've seen much weirder blended families work things out, so maybe I didn't need as much convincing about that aspect of the plot as the author thought I would. Other readers might have needed more help with the idea of the ex-and his boyfriend-and your boyfriend all hanging out with you, but I've seen it work before. I accepted that pretty much the attitude of "I believed you the first time," while the author kept going back and hitting the same chords over and over again. But that might have felt necessary for the more average reader going, "No way!"
The supernatural elements were what really killed the book for me. Something happens midway through the book that is never explained, never really handled, that then disappears again until the very end of the book. Then it comes back as a deus ex machina, popping up to give the story the "right" ending before disappearing again. Honestly it felt like the author wrote herself into a corner, then went back to a throwaway idea from an earlier draft and wove it back in to get to the ending she wanted. It was a clumsy feeling that didn't match the rest of the story. If this were a series I would hold out hope that this would be explained later, but I don't see any series information on my goodreads. So for now, it stands as the warning that there can be such a thing as too much genre bending.
