Crowned by Fire
Catherine Pierce always knew she was going to leave home. She just never thought it would be at seventeen, on the run for her life. Her only ally is her greatest enemy, Phineas Riordan, the witch who brought her to the attention of the Slayers hunting her. But Phineas is losing his control...and his sanity...and he is determined to possess Catherine at any cost. Even if it starts a war.
