Sorority Cold Case by Jacquelin Thomas

An unsolved murder. Two detectives with something to prove...

Detective Charlie Tesarkee has never forgotten the case she couldn’t solve. It’s been eleven years since a college student was murdered, and she’s desperate for a second chance to catch the killer. The Cold Case Unit will let her lead the investigation...if she works with Detective Grayson Leigh. A partner is the last thing Grayson and Charlie want. But they’ll have to work together to get justice for this victim...and put a murderer behind bars.
