Surrogate Mother For My Friend's Stepfather

Lila Hart has been in love with her best friend's stepfather since she was nineteen.
She never planned to act on it. Stefan Hale was off-limits-married, older, and completely out of reach. She told herself the crush would fade. It didn't.
When Lila found out he and his wife were looking for a surrogate, she saw a chance. Not for him-for the money. $75,000 to pay off her debt and finally start her life. A simple transaction. Nine months, then she walks away and forgets any of this ever happened.
But nothing about Stefan Hale is simple. And his wife? She knows exactly what Lila wants. She's just waiting for me to slip.
