The Cavanaughs are back to doing what they do best–fighting crime–in this electrifying new novel by USA TODAY bestselling author Marie Ferrarella!

For homicide detective Ronan Cavanaugh O'Bannon, this time it's personal! The body of a police friend is found executed in the same manner as rival gang members. There's no progress in finding Aurora's serial killer...until Sierra Carlyle joins the team.

The perky young newbie is as chatty and extroverted as Ronan is taciturn and closed off. She irritates him, but she's a brilliant, relentless investigator. Working together, Sierra's warmth begins to thaw Ronan's iciness. But acting on their undeniable attraction proves unwise now. There's a killer to find and stop...before he sets his sights on a Cavanaugh!
