What Is The Timeline Of The Summer I Turned Pretty

Okay, so you know how some shows just hit different? The Summer I Turned Pretty is one of those gems. But have you ever stopped to wonder about its whole timeline — from book to screen to that mega finale? Grab your iced coffee, because we're breaking it all down.

The Book That Started It All

It all kicked off with Jenny Han's beloved YA novel, The Summer I Turned Pretty, published back in 2009. Two sequels followed right after — It's Not Summer Without You in 2010 and We'll Always Have Summer in 2011. A trilogy in three years? Han was literally on fire, and honestly, good for her.

These books became an absolute phenomenon. Fans devoured them like beach reads, because well... they were beach reads. The triangle between Belly, Conrad, and Jeremiah? Chef's kiss of early teen heartbreak.

From Page to Prime Video

Fast forward to 2018 — the series was optioned for a TV adaptation. It took a hot minute to get to screens, but by 2021, things were finally moving. Jenny Han herself stepped in as co-writer and showrunner, which was the best decision anyone ever made, period.

The pilot cast dropped in late 2021, and fans lost their collective minds. Lola Tung, Gavin Casalegno, and Christopher Briney — the holy trinity of Casting Perfection. Like, were you even a stan if you didn't scream at your screen? Because I definitely did.
