Clashing Tempest

Finn de Morisco knows he is walking into a trap when he enters the Vampire Cathedral to rescue his sister Cynthia. Aided by Schwint and his other sister, Caitlin, he intends to free Cynthia and avoid enslavement. But when he confronts the master of the Voice that has tortured him, Finn faces a grim choice: compromise his soul or lose his family.

For centuries members of the Chromis tribe have disappeared, and Brett Wright is on a quest to discover the fate of the captive mers and to stop the abductions. Despite the risk of tribal warfare, he embarks on a dangerous ocean journey to find other mer tribes experiencing the same plight. When destiny brings him back to land, Brett encounters new allies and old dangers while coming to grips with the past.
