The first book from fantasy writer Mark Charan Newton

Has-jahn: a continent of exotic cultures, cities and long-forgotten technology. Two members of a race once thought extinct wash up on the shores near the city of Escha. In their possession is a call for help from a human living on the little-known tropical island of Arya, where their race is being murdered. A crew of freelance explorers, led by the charismatic Santiago DeBrelt, travels to discover the mystery behind the killings. However, Santiago's controversial nature leads to him being accompanied by government agents — who wish to explore Arya and find out why Eschan naval vessels have disappeared in the seas surrounding it.
