Entangled

Alone was the note Cade knew best. It was the root of all her chords.

Seventeen-year-old Cade is a fierce survivor, solo in the universe with her cherry-red guitar. Or so she thought. Her world shakes apart when a hologram named Mr. Niven tells her she was created in a lab in the year 3112, then entangled at a subatomic level with a boy named Xan.
   Cade’s quest to locate Xan joins her with an array of outlaws—her first friends—on a galaxy-spanning adventure. And once Cade discovers the wild joy of real connection, there’s no turning back.
