The single best part about this book are the predatory mermaids. I've read a lot of mermaid books lately, and none of them have been quite so dark as this one - and I loved the dark bits. The twist at the end was pretty good, although I could definitely see most of it coming, but the middle was flat. While I know Calder isn't really supposed to feel much emotion, I would have liked to feel the pull between his bond to his sisters and his budding relationship with Lily more. I'd definitely read the sequel if it was on sale, but I wish I hadn't paid $9 for this book. Mermen, Mermaids and Promises Broken, that is what started out this whole vengeance drive this not so nice fishes have going on. When you make a promise to the menfolk you better keep it ! Well, of course somebody didn't and the issues trickled down a few generations to the present time where a young father is hunted to pay for the sins of his father. His teenage daughter just happens to be the lucky pawn girl the mermaids direct their revenge towards. Oh what a jumbled mess of love, lies and murder. The merman in charge of making the girl lusty begins to feel more than lusty, and starts to question his evil step sisters and ends up in the fishbowl for it all. This family drama has some funky tones to it that, well you'll see if you read it. There is a lot of self doubt, a lot of should searching and of course budding romance. It all ended with a mild cliffhanger, that didn't leave me clicking immediately for book 2. I enjoyed it, but something was missing.
