After finishing her training, arson investigator Karin Bergstrom takes a job with a new investigative unit which, unbeknownst to her, is headed by her former mentor, Aaron Knight. Aaron had been more than her mentor. He and Karin had been unable to hide their growing feelings for one another. But then a ceiling collapse had changed Aaron’s life forever and ended his relationship with Karin. To bind a healthy young woman to a man who might never walk again seemed unconscionable to Aaron.

Now, thrown together by fate, can they keep their shared past from interfering with the daunting task of catching an ingenious arsonist? The long, hot summer tests their talents, their loyalties, and ultimately, their love.
