The heart-stopping conclusion to the New York Times and USA Today bestselling series.

Five years, six months, eight days…

It’s been eighteen years since Abigail was born with a hole in her heart. Five years since she collapsed on the soccer field. Five years, six months, eight days since she found out she was adopted.

Abby has spent five years wondering about the family she never knew and waiting for her eighteenth birthday. When Abby shows up on the doorstep of Chris and Claire Knight, her birth parents are overjoyed to see the little girl they lost eighteen years ago.

One summer is all they have to make up for the years they lost. But when opposing ideals collide, a summer of love soon turns into a summer of heartache.
