It gave her a second chance at life. After leaving Hollywood to host a San Antonio TV show spotlighting children with special needs, Cat fights to gain respect as a newscaster. She meets Alex Pierce, an ex-cop turned crime writer, who regards her as a woman, not as a heart patient. When fatal ""accidents"" begin killing the other heart recipients, Alex may-or may not-be her most important ally. With her new world turning sinister and a mysterious stalker shadowing her every move, Cat is caught in a dark maze of betrayal and secrets... and perhaps sees too late the mask hiding a killer's face.
