Midnight Between Us (The Timberbridge Brothers #4)
Claudia Y. Burgoa

But now Keir Timberbridge—the traitor, the boy I once loved more than life—is back. Barely alive. In my care. With no memory of who I am or what he did to me.
I should walk away. Hell, I tried. But I’m the only one who can keep him hidden, keep him alive.
This town still thinks I’m the girl who let him go. No one knows the truth—about the letters or what it cost me to survive.
Now we’re playing house in the ruins of what we once were: me, a doctor with too many scars, and him, the man who vanished without a goodbye. We sleep in separate rooms. Share meals like strangers. And every time I look at him, I remember the boy who made promises at midnight... and the man who shattered them by morning.
Because loving Keir Timberbridge was always going to destroy me.
And I might let it again.
