High Reward by Brenna Aubrey

He was looking for redemption. Instead, he found her.

After a rocky start, former Navy SEAL-turned-astronaut Ryan “Ty” Tyler and nerdy flight psychologist Gray Barrett discovered they worked well together. Ty managed to tame his playboy reputation, and cautious Gray got her first taste of adventure. They had a good thing going. Until a good thing turned into a smoking hot thing…and that turned into a falling-in-love thing.

Now Ty’s facing an impossible choice. Shake the demons of his past, or give up a future with the only woman he could ever love.
