Dr. Casper Rollins knows how to have fun. The love of his life, Kage Myers, lived every moment to the fullest before he died. Now, Casper goes skydiving, mountain-climbing, or on other adrenaline-soaked adventures when he wants to feel closer to his lost love.

Medical director Eric Holtz is married to his work—so much so his husband left him. But when his niece shows up, pregnant and in need of an ally, Eric suddenly has family again.

Unfortunately, her obstetrician, Casper Rollins, is sexy enough to turn Eric into a blushing adolescent.

What begins as a game to break Eric of his workaholic tendencies escalates into scorching sex and feelings that can’t be ignored. Casper never planned to give his heart to anyone other than Kage, and Eric won’t accept anything less.

If these two want a future, they’ll have to embrace the lesson Kage taught Casper long ago: You only live once.
