Flyboy by Sophia Summers

A cowboy pilot willing to do whatever it takes to win her heart meets a woman who might take a lot of convincing.

Colton Bushman is the fastest pilot to have ever flown with the Air Force. He flies with precision, but views rules more as guidelines than hardfast must-do’s.
Ivy Hatfield has spent years obeying every rule that ever was, even making up extra for good measure, so that she can overcome her brother’s reckless reputation and the mark on her record from a past mishap with her co-pilot.

When Ivy writes a letter of complaint to the Top Flight board, Colton chooses who he assumes must be a fiery, rigid, rule following matron to be on his team. But he soon learns that she is as daring as he ever was. And she learns that his swift action and advanced flying is more calculated than reckless. Will the two who start out as opposites find a way to true and actual love?
