Five years, six months, eight days….

It's been 18 years since Abigail Jensen was born with a gaping hole in her heart and five years since she collapsed on the soccer field, spending a harrowing three weeks in the hospital fighting for her life. Five years, six months, eight days since she found out she was adopted.

For five years, Abby has gone to sleep wondering about the family she never knew and waiting for her 18th birthday. But when her birthday finally comes, she hesitates. What if her birth parents want nothing to do with her?

But just one month after her birthday, Abby and her adoptive parents have a disagreement that sends her searching for the birth parents she never knew.

When Abby and her boyfriend Tate show up on the doorstep of Chris and Claire Knight, her birth parents are overjoyed to see the little girl they lost 18 years ago standing before them, beautiful and on the cusp of womanhood.

But the news of Abby's rebellion leaves Chris and Claire conflicted. They agree to let her and Tate stay with them for the summer, to catch up on all the years they’ve missed. But when their visit comes to a close, and they encourage Abby to return home, Abby can't decide what hurts more: feeling unwanted by her birth parents; being misunderstood by her adoptive parents; or the very real and painful hole in her heart.
