What's the Name of That Book??? discussion

I don't know if I'm doing this right, so if it's wrong, I'm sorry.
So far here's the plot from what I can remember: The main character (a girl in high school) is at school, and her parents pick her up and don't tell her why. I'm not 100% sure, but I think they flew to Brazil without telling her why. She finds out her parents are separating (I think) and finds out she's adopted by papers she found at the hotel. She runs away and ends up shaving her head to hide her identity, and ends up sleeping on the beach, where her bag with all her money is stolen. She doesn't eat for days so a cafe she previously went to gave her cheesy potatoes. She also was staying at a house for really cheap, and used their old laptop to search for her bio mom. Later on she got a job teaching children English and I believe she had a co-worker named Jessica, idrk. At some point in the book, she's hiding her identity and runs through a parade and kisses a stranger in the parade. I remember the book ending with her bio mother being hit by a car.
I'm sorry this is so badly explained, but I only remember some of the book, and the book was insane to read.

Missing at 17?

I know exactly what you’re talking about. It took me ages to remember the title but it’s “The Truth and Lies of Ella Black 40 days until she dies”

The Truth and Lies of Ella Black for the clicky
