Rainforest Honeymoon by Raeanne Thayne

Originally published as High-Stakes Honeymoon in 2007, New York Times bestselling author RaeAnne Thayne takes readers on a romantic journey to Costa Rica!

While honeymooning solo might be unconventional, ex-bride-to-be Olivia Lambert can't waste a fabulous trip to Costa Rica just because her former fiance turned out to be pond scum. Imagine her surprise when a handsome stranger appears in the jungle - silver machete in his hand!

Lucky for Olivia, Ren Galvez is a scientist and one of the good guys. And he was trying to save Olivia from a near-certain death at the hands of one of the bad guys. But who is going to save Ren from her?
