What the Heart Holds Safe [EPUB ebook] 

-a Delta Force romance story-
The round that took out the man behind Delta Force sniper D.K. “Deek” Davies missed him by inches. The problem? The man behind him had once been a friend—a friend with an inspiring sister who changed his future.
Cindy Borman’s lifetime of practice shutting away her heart means nothing when faced with the one man who knows her past.
Only together can they face What the Heart Holds Safe.
