Ask the Passengers by A.S. King

Astrid Jones desperately wants to confide in someone, but her mother's pushiness and her father's lack of interest tell her they're the last people she can trust. Instead, Astrid spends hours lying on the backyard picnic table watching airplanes fly overhead. She doesn't know the passengers inside, but they're the only people who won't judge her when she asks them her most personal questions . . . like what it means that she's falling in love with a girl.

As her secret relationship becomes more intense and her friends demand answers, Astrid has nowhere left to turn. She can't share the truth with anyone except the people at thirty thousand feet, and they don't even know she's there. But little does Astrid know just how much even the tiniest connection will affect these strangers' lives--and her own--for the better.

In this truly original portrayal of a girl struggling to break free of society's definitions, Printz Honor author A.S. King asks readers to question everything--and offers hope to those who will never stop seeking real love.

I borrowed the summary from Amazon. Ask the Passengers is a young adult novel about a girl who has to find herself. Astrid Jones is sending love to passengers in airplanes, which is quite original. Astrid can't talk to her mother and believes her sister Ellis is on her mother's side, they are slowly estranging from one another. There are parts of her life Astrid hasn't shared with anyone, but that's about to change. 

This book is all about secrets, Astrid has many and she's getting tangled up in them. She has to keep her best friend Kristina's and then there's her girlfriend Dee. Kristina's secretly gay and Astrid might be as well, but that's something she has to find out for herself. It's such a moving, beautiful and honest story. I was genuinely impressed. I think it's a great coming of age novel that I would recommend to everyone.
