Before and again by Barbara Delinsky

Mackenzie Cooper does not want to be who she was -- the one who was driving with her eyes on her phone just long enough to cause a deadly accident that cost her everything. In order to survive, she becomes someone new, someone better . . . until the past returns. Before and Again is a story of vital relationships -- mothers and daughters, spouses and siblings, true companions and fair weather friends -- and the courage it takes to make them work.
