Aveyond 4: Shadow of the Mist

Boyle Wolfbane tried and failed to take over the world. He's resigned himself to an early and mostly content retirement, until his pet wolf Fang goes missing. Meanwhile, the Mist Queen's son, Whisp, is kidnapped, and she sends her daughter, Myst, to find him. Fang and Whisp's fates become connected with both each other's and that of the entire world, pushing Boyle and Myst to work together and forcing Boyle to become what he hates most: a hero.
