After the End by Natasha Preston

One fatal mistake changes Tilly’s and Lincoln’s lives forever, and things will never be the way they used to be.
After the tragedy, Lincoln and his family flee the hometown they are no longer welcome in.
Four years later, still grieving the death of her brother, Tilly’s world is rocked again when Lincoln returns.

Distance and too much bad history haven’t stopped Lincoln from loving Tilly. He wants to beg for her forgiveness, but to avoid hurting her more, he tries to keep his distance from her … until he sees her fighting her feelings for him, and then nothing can keep him away.
