This started off good because you get a feel for the characters right away. Then everything goes slowly south. I think somewhere along the way, the romance is lost. Maybe its b/c Tessa was a hard character to like. She was very cold and standoffish. This book has alot of world building. In fact, the sisters don't really know much about their Mer side and world. The book mostly focused on a lot on the world building. But I'm curious to know what happens next. I just hope the author can do a better job at blending the mythological/paranormal aspect and romance together.
