Being a paramedic is a tough job; it’s tougher when you stumble onto a crashed alien spacecraft.

Melanie Mooney thought she was just doing her job when she came upon an unusual accident in the deep woods late one night. Acting alone, what she found was nothing like she’d expected. What followed was even more unexpected.

Recruited by emissaries of a galaxy-spanning civilization, Melanie is thrust into a world she thought only existed in supermarket tabloids. As the first human in the Galactic Union Medical Corps, she cares for extraterrestrials in desperate need of a medic who can ignore the fact that they’re nothing like any patient she’s ever seen, even on their best days. And in emergency medicine, it’s a given that every patient is having the worst day of their life.

Each run takes her deeper into the galaxy and farther from home, navigating alien cultures that only get weirder with each call. It will take all of Melanie’s experience, instinct, and grit to prove herself—and the rest of humanity—to be worthy of the Union. That’s a lot to put on a woman who’d just like to end the day with a cheeseburger and a cold beer.
