Ryker [EPUB ebook] 

After his last assignment, Ryker is ready for a rest. And he gets it—but only a few hours …
That’s even too long for a geologist kidnapped by guerrillas in the Columbian jungle. Ryker has plenty of experience in jungles around the world but, keeping Manila safe—along with the two men she’s traveling with and their injured guide—exposes them for who they are. It quickly becomes apparent, under these most gruelling conditions, which of her party steps up and which plan to step out.
Manila’s life has become one of never-ending misery at the hands of her captors as they await word from their bosses, who decide her ultimate fate. That she’s hunting platinum doesn’t matter to them. Nor that she’s fighting against the invasive illegal gold mining taking over parts of the area. When Ryker rescues her from her prison tent, she places her trust in his ability to get her and her team safely away. Not yet realizing she’d be gifting him both her body and her heart too.
Ryker needs to keep them all alive and together long enough to get them out of this hellhole—hopefully alive …
