Complete version of previously serialized stories.
-a Shadow Force: Psi romance-
Delta Force recon specialist Hannah Tucker needs out of the Colombian jungle and she needs out now.
Night Stalker pilot Jesse Johnson aims to oblige...until his helicopter is shot down. He finds that more than a little inconvenient.
Stalked by guerillas, crocodiles, and other jungle unfriendlies, they must learn to control skills they never knew they had - or even existed!
Together they discover an unpredictable psychic ability to project sound and distract their enemies. Though the crocodiles remain unimpressed.

Their introduction to a secret military force, whose unique psi talents lay hidden in the shadows, launches them into a whole new world they never imagined.
