Tomorrow Belongs to Us by Lily Zante

A young woman’s life is disrupted when she reconnects with the high-school teacher she fell in love with.

Lance Turner wanted to help the bright young student whose grades were slipping, but he struggled to fight the sizzling attraction between them.
The feelings he had were forbidden. What they wanted could not be.
Unlike the other girls in her class, Megan didn’t fall for the sexy, young teacher.
But her feelings soon changed when her world imploded and Mr. Turner was the only one who noticed.
He was the only one who seemed to care.
He was good to her. He listened. He was her safe haven. But his sudden departure left her devastated.

When they meet a decade later, all she wants is closure but all he wants is a second chance.

TOMORROW BELONGS TO US is an age gap, second chance, steamy, slow burn romance about taking chances and allowing new beginnings.
