The Billionaire Bachelor by Ashley Zakrzewski

Sexy as sin, broody and mysterious, Dawson Carter is the ultimate bachelor.

For the last twenty years, Dawson has guarded the gate to his heart, not letting anyone in. He broke the number one rule of friendship, falling for his best friend in high school.
Maci is the kind of woman that holds her own – and then some but when Dawson is around, she acts like a teenager again.
When the two go back to their hometown of Grapevine, Texas for their twenty-year high school reunion things get hot.
Will Maci speak her truth or will Dawson be forced to move on?
