Lose You to Find Me — B. Celeste

After Raine Copelin turns down her long-time boyfriend Caleb Anders's marriage proposal, the two are barely speaking, barely coping as they enter graduate school at Lindon University. Caleb doesn't understand what happened -- their relationship has been picture-perfect since high school. He always imagined starting a family together, the same happily ever after his parents had. Until the day she broke his heart, he thought Raine wanted that, too.

But Raine has her reasons. Her secrets. She knows she can't give Caleb the future he wants, so she decides to let him go, no matter the price she has to pay. But when fresh tragedy sends Caleb spiraling back into Raine's arms, the unanswered questions between them bring old feelings and new wounds to the surface. Fighting grief, lies, and fear, the two must figure out if their love ever truly ended, or if their uncertain futures might still include each other.
