This book was like a breath of fresh air when it comes to mysteries. Sarah Danger, a clairempath, works as a PI in-training for her friend's, Jeff, agency. They take a case in Hawaii that involves a mystery virus that is spontaneously heating people up from the inside. They will be investigating what caused it; whether natural or supernatural. Once on the big island, Jeff has a minor heart attack which puts him on bed rest. This leaves Sarah to step up to lead investigator. She isn't too sure but she does what needs to be done. With the help of the rest of the team, Sarah interviews the people involved and hikes the volcano park where the scene seemed to start. Needless to say, Volcano activity; Pele; cheating; revenge; and rituals are all part of the puzzle. A lot of puzzle solving with this one. Good book that leaves you thinking. Intriguing facts about Hawaii and Hilo. Highly recommend. ( )
