“After You,”  by Jojo Moyes.

After the transformative six months Louisa Clark spent with Will Traynor, she is struggling without him. When an accident forces Lou to return home to her family, she ends up in a church basement with the members of the Moving On support group, who share insights, laughter, frustrations, and terrible cookies. They will also lead her to Sam Fielding—the paramedic, the one man who might be able to understand her. Then a figure from Will’s past appears and hijacks all her plans, propelling her into a very different future. For Lou Clark, life after Will Traynor means learning to fall in love again, with all the risks that brings. Jojo Moyes gives us two families, as real as our own, whose joys and sorrows will touch you deeply, and where both changes and  surprises await.
