Trial by Fire — J.A. Jance

In the heat of the Arizona desert, a raging fire pushes temperatures to a deadly degree, and one woman is left to burn. Pulled naked and barely breathing from the fire, the victim has no idea who she is, let alone who would do this to her -- or why. Then a savior appears. Sister Anselm is a devoted advocate for unidentified patients, but to Jane Doe's remorseless would-be killer, she poses a serious threat. Ali Reynolds, the police department's new media consultant, circumvents questions about arson and a link to a domestic terrorist group as she struggles to help Sister Anselm locate the missing relatives. But their efforts may be exposing the victim once more to danger. In the fearless pursuit of justice, Ali discovers a secret even darker and more twisted than she ever could have imagined.
