Paper Cranes by Jordan Ford

Tristan Parker is lost.
After living through his parent’s bitter divorce, Tristan surprises everyone when he decides to uproot his life and move across the country with his dad. Disenchanted, Tristan deals with his pain by shutting out the world… until one day, when trying to retrieve a lost baseball, he climbs a tower and meets a girl.

Helena Thompson is like no one Tristan has ever encountered. She’s quirky, weird, and lives in an imaginary world—her only way of coping with the bizarre life her paranoid mother forces her to lead. Drawn by Helena’s magical view on life, Tristan finds himself returning often to the unique girl with the long golden hair. But spending time with her is not an easy task, especially because their relationship must be kept a secret.

When Helena’s mother discovers the truth, can Tristan find the strength to fight for the girl who has awakened his heart? Or will the paranoid woman who keeps her daughter under lock and key stop their dreams from coming true?
