Dark Winds: Shadow's Fire Book 2 - Dream Walker Chronicles, #2

Erik has killed men. Death haunts his dreams. Fate has chosen its path for Erik Eleodum...or has it. The pain of killing seems to overwhelm him as he grows more and more distant from his brother and cousin and he turns into the very person he once loathed...a thief, a mercenary, a killer...a hero. Erik must not only face dwarves, murderers, slavers, dragons, and the undead, he must now face his fears, the darkness that has been hidden deep inside of him.
Take a journey that will shatter worlds, stain hands red with blood, test faith, question loyalties, make strong men weak and weak men brave. The world is changing and a great evil is rising, all carried by Dark Winds!
