Angelfire Trilogy, Book 2: First Love by Karen Wiesner

During a traumatic childhood, Darlene Foxx had only one light--Jason Radcliffe, her best friend and eventually her lover. Until she found out that she wasn't his only lover, Darlene dreamed of the day they'd escape and be together forever. At seventeen, she left home alone and forced herself to overcompensate for her upbringing by never trusting anyone, especially Jace.

Years later, Darlene is in desperate need of a friend to share her joy, her fear and past secrets that have haunted her. Maybe she can even share her heart with her first love, forever.
