The Summer I Turned Pretty by Jenny Han #1

The Summer I Turned Pretty is now a major new TV series on Amazon Prime!
One girl. Two boys. And the summer that changed everything . . .
Every year Isabel spends a perfect summer at her favourite place in the world - the Fisher family's beach house. It has everything a girl could want: a swimming pool, a private stretch of sandy beach... and two (very cute) brothers:
Unavailable, aloof Conrad - who she's been in love with forever
Friendly, relaxed Jeremiah- the only one who's ever really paid her any attention.
But this year something is different. This year, the boys seem to really notice Isabel for the first time. It's going to be an amazing summer - and one she'll never forget . . .
