Pawn, Book 3 of The Turner Chronicles

In Betrayed, Aaron Turner defied politicians, defeated child slavers, and saved an entire people from exploitation by Isabella, his adopted country. Now, ten years later, he and Isabella have parted ways. Aaron has moved across the ocean to Jutland, intending to run a men’s clothing store in the small city of Galesword. Unfortunately, his lawyer and the One God have other plans. An emperor covets him. Heads of governments abhor him. Assassins and slavers and pirates want him dead. A lot to handle for a slightly built man with a Talent Stone and a growing dependency on wine, but Aaron is up to the challenge. Until his Stone is lost, his daughter is kidnapped, and the emperor reveals his plans.
