"The Summer I Turned Pretty" ($9) centers on Isabel "Belly" Conklin, who, for as long as she can remember, has spent each summer at Cousins Beach with her mother's best friend's sons, Conrad and Jeremiah. During her latest trip, Belly notices that the brothers have done a lot of growing up since she last saw them, and they feel the same way about Belly, who's on the brink of turning 16. As the summer progresses, Belly's relationships with each of the Fisher brothers begin to change when they all get caught in a love triangle.
