Jahle by Delia Roan

Melissa Harlock scoffed at her sister’s stories about extraterrestrial life. That is until she’s kidnapped and whisked away to a desolate planet. Her alien captor makes her toes tingle, but Mel isn’t the kind of woman to give up her freedom – or her heart – without a fight. Something sneaky is up, and she wants out.
Ennoi prince Jahle’s loyalty is tested when his feisty prisoner takes him hostage and demands an escort to safety. The jailbreak is the perfect cover for a secret mission that could save Jahle’s people from his brother’s cruel reign. He just has to hide his deception – and his growing desire – from Mel long enough to succeed.
Hunted by Jahle’s angry brother, the lovers must rely on each other to survive a wasteland ravaged by earthquakes, giant centipedes and dangerous storms. With Jahle’s brawn and Mel’s brain, they’re the perfect team. Except… they’re supposed to be enemies, right?
