Protective Hearts [EPUB ebook] 

Finn is the only surviving victim of the Chicago Heart Ripper.
Struggling to come to terms with what happened, she fights against the amnesia that prevents her from identifying the serial killer.
Caleb Sheppard is determined to protect Finn. He suspects that there is more to the prolific serial killer than meets the eye; why did he leave Finn alive?
With the Ripper on their heels, they race against time to retrieve Finn’s memories, keep her out of the murderer’s clutches, and discover the secrets of his identity.
What Finn does not realize is that Caleb is hiding secrets of his own – some of which she might not be able to accept.
