Harmonies of Tekrosen. Strains of Portomare, #3

A city in the trees. A jealous eldsinger. A disaster waiting to happen.In the search for hidden peoples in their ocean, siblings Trace and Echo and their friends locate a world that's nearly dead, half of the reef filled with urban ruins. Along with the ruins are trees, huge trees unlike anything anywhere else in the world, trees that hold an entire city of people and some of the darkest evil the group has discovered so far. They also discover two young, strong eldsingers who have felt one another's presence their entire lives.
While the pair learns to use their strength, Trace finds that on this reef he has a strange singing handicap that makes him the least useful person in the group. Hating that he's jealous, he works overly hard to prove himself, drawing his whole team into danger. If he can't come to terms with the power of his new friends and his place in these worlds, this reef and its people might not survive. Harmonies of Tekrosen is book three of the Strains of Portomare series, fantasy about an underwater world and the powerful men and women who travel its currents.
