Forever with the SEAL — Amy Gamet

All of the HERO Force books can be read as standalone stories.

Trevor “Hawk” Hawkins and Olivia Grayson are finally going to marry, but she's finishing up a film before they say “I do.” When someone starts stalking her, Hawk must go overseas to protect the woman he loves -- but a ghost from his past may draw him away from HERO Force forever.

This is a novella, not a full-length book.
