Come Midnight by Kat Martin

A routine flight turns into a suspenseful race through the remote jungles of Honduras

When strangers Breanna Winters and Derek Stiles met on a flight to Colombia, they never imagined they would need to rely on each other for survival. Taken hostage by a group of radical environmental vigilantes, Bree worries her secret identity has been discovered—and her fears are confirmed when she learns a ransom request has been sent to her father. Though she’s the daughter of a prominent tech mogul, Bree’s wealth can’t guarantee her safety, so former Navy fighter pilot Derek pretends to be her fiancé in order to accompany her on a dangerous jungle trek led by the radicals. With chemistry building between the pair, a romance isn’t hard to fake, though they can’t let their attraction distract them. If Bree and Derek ever want to see civilization again, they’ll have to work together and rely on their wits to escape their captors.
