Isabel Belly Conklin (Lola Tung) and her mother and brother are spending the summer at a cousin's beach.

Her mother's lifetime best friend and her sons, Jeremiah (Gavin Casalegno) and Conrad, join the group (Chris Briney).

Crushes and romance take off quickly, kicking off a string of first loves, first heartbreaks, and an emotional roller coaster.

Next month, The Summer I Turned Pretty will be available on Amazon Prime. Jenny Han is the author of To All The Boys I've Loved Before, and this is her second novel trilogy to be adapted into a programme.

The series follows adolescent Belly (Lola Tung) as she spends her summer at her family's beach property reconnecting with old pals, but things don't go as planned.

Isabel "Belly" Conklin, as always, is looking forward to a beautiful summer at her family's home in Cousin's Beach. This summer, however, something is different.

While she reunites with her friends Conrad (Christopher Briney) and Jeremiah (Gavin Casalegno), the former of whom she had a crush on before, things seem to alter, resulting in a love triangle between her and the two brothers.

Belly begins a love involvement with one of the brothers toward the end of the novel (but we won't tell you which one).
