Forbidden River by Brynn Kelly

A dangerous game at the end of the earth…

For French Foreign Legionnaire Cody Castillo, chasing deadly thrills is the only reprieve from a bloodstained past he can't forget. But when the adrenaline junkie finds himself caught in a mass murderer's crosshairs in the lonely wilds of New Zealand, he finds an unexpected–and intriguing–ally.

Former air force pilot Tia Kupa has always found safety in nature, until a killer turns the wilderness into a playground. In this life–or–death game, the guarded woman who lives by the rules must rely on a risk taker with a death wish. The sexy devil–may–care legionnaire may be the wrong guy for her, but desire is just as primal as terror. Even if they outrun a predator, they can't escape the sizzling bond neither of them saw coming.
