NASA Flight Surgeon Dr. Rebecca Sato is ready for the next frontier... a family.

At thirty-six, the men on Rebecca's radar are either intimidated by her intellect or not interested in having kids. So when not in charge of NASA's astronauts and their health, she devotes her spare time and energy to the local animal shelter.

At twenty-eight, Houston Lieutenant Firefighter Ryan Cassidy knows he's an old soul.

Tired of girls his age who only crave a quick hook-up with a good-looking fireman, he's ready to settle down with a wife, kids, maybe a dog.

When a fire at Johnson Space Center threatens NASA's medical building, Ryan rushes in, ready to take charge. But he's blindsided by a calm, compelling doctor who's already in command of the evacuation. While the fire is easily contained, Ryan can't say the same for his heart.

Attraction fans the flames, but dating a younger man is not in Rebecca's comfort zone. Determined to synchronize their orbits, Ryan volunteers to pose for her animal shelter's charity firefighter calendar. Between Ryan's abs and his love for animals, the wall around Rebecca's heart starts to fall. Will their age difference be too much to overcome?

Or will they achieve a five-alarm lift-off?

*Space Age is the prequel to the bestselling Space Series and features a younger man who agrees to go topless for a fundraiser calendar after falling first for the animal shelter volunteering NASA flight surgeon who's looking for Mr. Right in an older age bracket.
