Deep Betrayal    by Anne Greenwood Brown Order:  USA  Can Delacorte, 2013 (2013) Hardcover, e-Book      Reviewed by Ricki Marking-Camuto The second book of a trilogy often serves as simply a bridge between the first and last books. While Anne Greenwood Brown does use Deep Betrayal in this manner, it is a bridge full of twists and turns that will keep the reader fully engaged. After her thwarted sacrifice of herself to Calder's sisters in exchange for her dad's life, Lily Hancock finds herself back in her home state of Minnesota, about to graduate high school with the rest of her friends. While she likes being with her friends, she longs to be back on the shore of Lake Michigan and with Calder, whom she has not seen in over a month. After graduation, Lily's parents allow her to move back home, but she has to promise both her dad and Calder that she will stay away from the lake. However, she feels drawn to the water and quickly breaks her promise, discovering that, while she does not have a tail, she has inherited some mermaid abilities from her dad ... who just discovered his strange origins. While her dad is spending more and more time in the lake and away from the family, kayakers are being capsized, leading to rumors of large fish and riptides. Lily and Calder know it must be his sisters trying to feed while delirious with hunger. Or could it be that her dad, newly transformed, cannot control his merman desires? Whatever the cause, Lily and Calder must work fast before more people get hurt. What elevated this beyond most middle books of trilogies is that Lily still experiences character growth and that many revelations come to light. The mystery of the strange lake activities also adds an extra dimension to Deep Betrayal, making it more than just a connector between Lies Beneath and Promise Bound. Deep Betrayal adds some new depth to Lily and Calder's story. I, for one, cannot wait to see how Anne Greenwood Brown ends this exciting and unique mermaid tale.
