Risk-averse event planner Amerie Price is jobless, newly single, and about to lose her apartment. With no choice but to gamble on her shaky start-up, the last thing she needed was to run into her smug ex and his new, less complicated girlfriend at Amerie's favorite coffee shop. Panicked, she pretends to be dating the annoyingly sexy man she met by spilling Americano all over his abs. He plays along--for a price.

Half the single men in Houston claim to be astronauts, but Vincent Rogers turns out to be the real deal. What started as a one-off lie morphs into a plan: for the three months leading up to his mission, Amerie will play Vincent's doting partner in front of his loving but overly invested family. In exchange, she gets a rent-free room in his house and can put every penny toward her struggling business.

What Amerie doesn't plan for is Vincent's gravitational pull. While her mind tells her a future with this astronaut is too unpredictable, her heart says he's exactly what she needs. As their time together counts down, Amerie must decide if she'll settle for the safe life--or shoot for the stars.
