The story starts with young Isabel "Belly" arriving at the Summer house, a house that belongs to her mother's best friend, Susannah. Belly has been going to that house all her life and she's grown up with Susannah's two sons Conrad and Jeremiah. Conrad is the eldest, two years older than Belly, he's quiet, reserved, studios and the natural leader. Jeremiah is a year older than Belly and he's the fun, happy, funny one who is Belly's best friend. Belly has been in love with Conrad since she was 10 but he's never seen her as anything other than a little sister. The first book begins with this innocent plot, a girl turns 16 and suddenly both boys begin noticing her as something else. The first book is phenomenal. Almost 5 star review. You have a wonderful sort of innocent that permeates the story, took me back to when I was her age and the magic that Summers and boys held. Belly is very innocent and doesn't see where Conrad's moodiness is coming from until the end and it is heartbreaking. Jenny Han does such a good job of stabbing you in the feels in this one, it comes nearly unexpected and it's like a tidal wave. The first book ends in a solid note, honestly Jenny Han could have stopped there but she crafted the rest of the series very well.
