In a heartbeat

the long version

With that brief, terrifying phone call, Lisa Langley's nightmare began again. Four years ago she was the sole survivor of the Grave Digger, a madman who buried his victims alive. Now a copycat killer is on the loose and she's the only chance Special Agent Brad Booker has of stopping this twisted psycho before more women -- including Lisa -- die. Hard-edged and always in control, Booker has never forgiven himself for failing to save Lisa from falling victim to the first Grave Digger. Whatever it takes, this time he's not going to let her down. Because almost losing Lisa is not something he can live through twice . . .
