A medical miracle gives TV personality Cat Delaney more than a new heart. With her second chance at life Cat trades Hollywood for San Antonio, where she hosts a TV show for children with special needs and meets Alex Pierce, an ex-cop turned crime writer.

But her new world turns sinister when fatal "accidents" begin killing other heart transplant recipients, and a mysterious stalker starts shadowing her every move. Soon Cat realizes Alex may or may not be her most important ally - and that her new heart comes at a terrible price: a tangled web of secrets and someone determined to take her life.
