One minute, Casey Shea was minding her own business, doing her job, teaching entomology to college students, and the next she was in the middle of the Costa Rican, jungle fighting for her life. Troy "Beatle" Lennon has watched his friends fall head over heels in love, but never thought it would happen to him. Until he sees a picture of his teammate's sister. That was it. The absolute joy in her eyes calls to him in a way he can't understand. But that joy is currently being threatened by an unknown person who had Casey kidnapped and hidden deep in the jungle. It's up to Beatle to find her and keep her safe until the threat can be neutralized. Surviving the dangers of the jungle turns out to be the easy part...staying ahead of the killer is much more complicated...and deadly. **Rescuing Casey is the 7th book in the Delta Force Heroes Series. Each book is a stand-alone, with no cliffhanger endings.
