Who Belly, Conrad, and Jeremiah End Up With in the "Summer I Turned Pretty" Book Series

Susannah dies from cancer between the first two books. Before her passing, her relationship with Conrad and Jeremiah's father doesn't improve as much and we don't see her love life progressing any further.

Laurel also doesn't receive a romantic storyline in the books, although she is divorced from Belly and Steven's father like she is in the show. Her and Susannah's strong friendship and their bonds with their kids are the extent to which we see any character development for them.
