Reviews

[Laura Poppenwimer]

A good mystery thriller novel with a complex plot. The characters are well developed and their relationship adds to the storyline and partnership helping to solve crimes. Once you get into the book, it is hard to put down.

Murderous Excitement

The action in this serial killer's debut is superb...right from the start. It keeps you on your toes throughout. Excellent detective skills.

Another gripping tale if the Lake Superior killer. Another chase. How long until she finds him. Who will survive??
