Never Say Die - Tess Gerritsen

"You're on a fool's errand. Surely you know your father is dead."

Twenty years after her father's plane crashed in the jungles of Southeast Asia, Willy Jane Maitland was finally tracking his last moves. She recognised the dangers, but her search for the truth about that fateful flight was the only thing that mattered.

Without knowing who to trust, Willy turns to ex-army officer turned mercenary Guy Barnard. He knows the jungles like the back of his hand, but Willy can't be sure who he's really working for.

As deadly assailants chase them, Willy and Guy realise they're investigating secrets people will kill to protect.
