"The Power" by Naomi Alderman
It made man Best of 2017 lists, has won awards, and was the first thing on Obama's 2017 list.
It is a very good book for a young lady your age. You will identify with many of the characters in this book.

When I was your age I really enjoyed Rats Saw God and The Giver. Brave New World and Do Androids Dream of Electric Sheep might be good dystopian options.
