8 HOURS TO STOP AN EXPLOSION ... 8 HOURS TO FALL IN LOVE. From the NYT bestselling co-author of Illuminae and Aurora Rising comes a high-octane, high-chemistry, sci-fi adventure about a stowaway girl and the richest boy in the galaxy, racing against 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 - equal parts national pride, and corporate power grab. Enter Hunter Graves: handsome, ambitious, and with spectacularly bad timing. He shows up unannounced at the United Nations base just in time for a toxin alert to set off every alarm they've got. Then the evac pods leave without him. Also stranded: Cleo, a sharp-tongued stowaway with no intention of dying today, and even less patience for overconfident trust fund boys. But the enemy of your enemy is the jerk who might just help you survive. There is no toxin. There is a team of invading mercenaries planning 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.
