Grace Adams is one bad day away from saving her life.

One hot summer day, stuck in traffic on her way to pick up the cake for her daughter’s sixteenth birthday party, Grace Adams snaps.

Today she’ll show her daughter that no matter how far we fall we can always get back up again. Because Grace Adams was amazing. Her husband and daughter once thought so. They and the world might have forgotten.

But Grace is about to remind them . . .
