8 HOURS TO STOP AN EXPLOSION...8 HOURS TO FALL IN LOVE.
From the New York Times bestselling co-author of Illuminae and Aurora Rising comes a high-stakes, high-chemistry, sci-fi romp about a stowaway girl and the richest boy in the galaxy, racing the clock to outwit a gang of mercenaries.

It's 2067, and the Graves family has transformed Mars from a lifeless rock into a chaotic patch of settlements. You can buy a one-way ticket to a new life--if you're rich.

Enter Hunter Graves, the handsome, ambitious grandson of the man who settled Mars. With spectacularly bad timing, Hunter arrives at the United Nations base just as an emergency evacuation sends everyone scurrying for safety. Except he's left behind. Uh-oh.

Also stranded: Cleo, a sharp-tonged stowaway with no intention of dying today, and even less patience for overconfident trust fund boys. But the enemy of your enemy might just help you survive, so here we are.

It turns out the evacuation is just a cover for the mercenaries who come next, and the plan to blow up the base--and every trace of their crime--in eight hours.

Now, Hunter and Cleo have one shot to stop the explosion, escape alive, and deal with the inconvenient fact that they're falling for each other.

The clock is ticking.
