Cavanaugh Standoff. Marie Ferrarella

For homicide detective Ronan Cavanaugh O'Bannon, this time it's personal…and totally baffling! 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. Frankly, she irritates him, but she's a brilliant, relentless investigator. Working together, facing danger, 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!
