Mercy Gunderson has quickly become one of my new favorite heroines. Fierce and fun with some added attitude, Mercy follows the likes of Eve Dallas and is sure to be as successful and well-loved as J.D. Robb's epic heroine. Mercy has that same grit and drive and her keen instincts make her a great FBI agent. Though far from perfect, Armstrong creates a heroine that readers can relate to.

Mercy hasn't even settled in yet before her first murder case involving a young girl forces her into action. The victim is the niece of a recently elected tribal president whose media coverage is in high demand. Adding to that pressure is Mercy's personal life where her boyfriend, Eagle River County sheriff Mason Dawson brings his eleven- year-old son into their home after he's been getting into fights at school.

Balancing her professional career with her personal life has been a tough juggle for Mercy and this struggle follows her throughout this book. As the mystery escalates and another killing occurs, Mercy and her fellow FBI agent Shay Turnball contemplate the possibility of connected crimes.

Armstrong takes readers on an intense ride. Unforgiving in its graphic details and plot twists, Armstrong delivers a mystery that is pure perfection! MERCILESS is mystery done right!
