I know these are annoying, but this story just won't leave my mind.
It's a Claire and Quil story. Claire is taken away by her parents at a young age. Ever since, she develops this condition that no doctor has ever been able to diagnose. Basically, she uses crutches and has intense pain in her legs, etc. Her health is deteriorating, and the doctor says she only has so much longer to live. She decides to move in with Emily for her final days, and her parents consent. But when she gets there, she and Quil slowly reconnect, and she gets better.
That's all I really remember. If you know the name, please tell me! I tried looking for it, but couldn't find it anywhere. Thanks!
