I had to think about this review for a couple days. There isn't much you can say without giving away too much, so I'll tread with care here.
Waking Hours has a little of everything - strange phenomena, a chilling murder, a touch of the supernatural, and a pair who met in high school and are reconnecting. Dani Harris shared a dance with Tommy Gunderson in high school. She was bookish and quiet and he was a football star. The relationship went nowhere in high school. They meet again later in life under circumstances that bring them to the heart of a grisly murder. Dani, turned psychiatrist and is working on consult for the police department and Tommy, retired from pro football, harbors an interest in becoming a PI. Dani and Tommy end up investigating a crime that defies logic. Wiehl doesn't go through gratuitous violence here, which was a relief. Thus begins our journey with Dani and Tommy into a life-changing investigation.
Told in third person, the story is limited to the thoughts and feelings of just Dani and Tommy, which enhanced the mystery. You are kept guessing who committed the murder at the start of the story. The whole story is veiled in the supernatural. I couldn't wait to finish this story, just couldn't wait to see what was going to come next. The story was complete on its own, but did leave a couple strands of the story untied, likely for a book two in this series. I look forward to book two, not just to tie up loose ends, but to continue an adventure with characters who are so well created and well rounded that I can't wait to read more.
