Brooke Leighton used to be just like everyone else: young, in love, and living her best life ... until her twin brother was murdered on the night of their twenty-first birthday. Seven years later, the mystery of Bobby's unsolved death has fueled an unquenchable thirst for justice and a rising career as a homicide detective for the Scottsdale, Arizona police department.
Even though Brooke has worked hard to move on and build a life for herself, her birthday is still a constant source of discord, and she often struggles to get through the day. This year is no exception when a ghost from her past crashes her party, sending her carefully reconstructed life into a tailspin and unearthing everything she's worked so hard to bury.
Thankfully she's got her extremely demanding job to help take her mind off things … or so she thinks.
While investigating a new string of murders in the area, Brooke comes face to face with a large wolf, but she won't escape this encounter unscathed.
With more than just the physical scars to remind her of the night her life was unknowingly and irreparably altered, an entirely new world is opened up to Brooke when the next full moon rises.
