In This Moment by A.D. McCammon

After tragedy turned Elizabeth Shea’s world upside down, she was lost—unable to let go of the past and unwilling to face the future.

Until she meets a handsome stranger, and their unlikely friendship breathes new life into her. He’s the last thing she expected, but exactly what she needs.
Since a near fatal night, Brenden Scott has been living in the moment. He doesn’t do relationships or believe in love.
Yet he’s instantly drawn to Elizabeth. He knows pursuing her is a bad idea, but she heals parts of him he didn’t even realize were broken.
When emotions get involved and lines start to blur, they find themselves standing at a crossroad.

Brenden wants something more than Elizabeth can give.
After all, you can only have one love of your life—
And she already lost hers.
