Calamity / Constance Fay.

"The captain of a ragtag mercenary ship is given an offer she can't refuse by the ruthless head of an intergalactic noble family. The only catch? She'll have to team up with his son--an upsettingly competent hardbody with his own agenda--to get her reward. She's got a ramshackle spaceship, a misfit crew, and a big problem with its sexy newest member... Temperance Reed, banished from the wealthy and dangerous Fifteen Families, just wants to keep her crew together after their feckless captain ran off with the intern. But she's drowning in debt and revolutionary new engine technology is about to make her beloved ship obsolete. Enter Arcadio Escajeda. Second child of the terrifying Escajeda Family, he's the thorn in Temper's side as they're sent off on a scouting mission on the backwater desert planet of Herschel 2. They throw sparks every time they meet but Temper's suspicions of his ulterior motives only serve to fuel the flames between them. Despite volcanic eruptions, secret cultists, and deadly galactic fighters, the greatest threat on this mission may be to Temper's heart."-- Provided by publisher.
