Eight hours to stop an explosion . . .
Eight hours to fall in love.

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

Enter Hunter Graves: handsome, ambitious, and with spectacularly bad timing. He shows up unannounced at the United Nations base just as an emergency evacuation sends everyone scurrying for safety. And he’s left behind. Uh-oh.

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, so here we are.

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.
