I Hope This Doesn't Find You (en Inglés) - Ann Liang

Seventeen-year-old Sadie Wen is perfect on paper. It’s a
reputation she’s fought hard to earn at the highly prestigious
Woodvale Academy, and one she’s determined to maintain

blatantly copied her science project and took the credit for it.
But most of her vehemently-worded emails are for her smug, infuriating
co-captain, Julius Gong, who’s been the sharpest thorn
in her side ever since they were kids. Sadie never meant for
these emails to get out ... but now her whole life is about to change...
