Haven Divided: The Dragon's Brood Cycle, Book 2 (Unabridged‪)‬

Emily Haven and her friends have been given the seemingly impossible task of uniting the worlds - a mission they failed once before, in another lifetime. But Emily made a promise, and she intends to keep it. A small boy risked his life to save hers, and while Michael sets out to rejoin the Dragon’s Brood, she heads east with Celine and Corbbmacc to rescue Daniel from a band of desert slavers. 

Time does not stand still, however, and the dark legends are true. They deal in blue fire; they deal in death; and they travel through the long nights on autumn winds. Samhain has come, and this year, the harvest will be in blood, gold, and souls.
