Killjoy - The Big Shot Savages, #1

Callie never expected to come face to face with Killian again. The boy she flew across the country to get away from at his insistence years ago. The cruel boy who tormented her at every opportunity.

Secrets that could bring Killian to his knees.
It's about time someone did.
