A meticulously constructed plot, rich characters and an all-too-feasible premise make this book a tough one to put down. It's by turns fascinating and unnerving.
There's something strange about the seemingly accidental death of a family in a national park in Alberta, and Royal Canadian Mounted Police officer Daniel Graham is determined to get to the bottom of it. Given some leeway by his superiors because of a recent tragedy in his life, Graham heads south of the border to investigate. The trail leads him to Maggie Conlin, who's living a nightmare after her husband, Jake, came back from Iraq a changed man. Now he's disappeared with their son, Logan, and the police have done little.
Graham doesn't know that Maggie is the link to a terrorist plot to assassinate a major religious figure, or that time is quickly running out. In the end, six seconds will change everything -- if Graham can't put the pieces together. (MIRA, Jan., 496 pp., $6.99)
