Proof of life

the long version

"CSI investigator Shanna Dawson has never forgiven herself for the long-ago disappearance of her little sister, Skylar. For fourteen years there have been no leads--or proof of life. Until now. Until Skylar's fingerprints implicate her in a murder at a fraternity house. Shanna is desperate to find the young woman. And so is handsome campus cop Quinn Murphy--the victim's half brother. But as their team investigation leads to an unexpected closeness and the revelation of family secrets, Shanna prays that her sister is innocent. And that the real killer is caught before Quinn is hurt, or Skylar is lost forever"--Publisher.
