It's Always Been You — Leanne Tyler

Retired Staff Sergeant Seth Roberts returns to Summerville to begin the next chapter of his life. To do that, he needs to find out why his girlfriend married another man more than twenty years ago while he served in the Persian Gulf. Their high school reunion is the perfect place to confront Elyse Jordan.
Determined to be a strong role model for her daughters, Professor of Feminist Theory Elyse Jordan never talks about the loss of her only love twenty years ago. Caring for her mother during cancer treatment brings Elyse back to Summerville, the one place she avoided after Seth's death. When an invitation to her twenty-fifth reunion arrives, she decides to go and reconnect with lost friends. She never imagines she'll come face-to-face with Seth instead.
Can Seth and Elyse find the thread of love that bound them together or will past tragedies and misunderstandings keep them apart?
