14 Big Differences Between the Summer I Turned Pretty Books and the TV Show So Far

The title of Laurel's upcoming memoir is not just a heartfelt nod to the second book in the Summer trilogy but a tribute to Susannah. It's established from the beginning of the show that Laurel's not going to be a side character, unlike her literary counterpart who largely stays in the background until she shows up for the kids and helps them keep Susannah's beach house.

In the second season, we see the role Laurel played in caring for Susannah and how she struggles to move past her death to the point where she's grown distant from her kids. Despite writing a book about their friendship, she refuses to promote it until Belly accuses her of being unable to deal with her grief.
