SOLVED. Spinal cord injury, young and old people, leading to tragic/controversial ending, probably set in past [s]

I don't remember much about this book. I read it in about 2010.
-The main character was young and had something irreparably wrong with his or her spinal cord.
He or she was in some sort of asylum. Because of this, I think the book was set in the past.
He/she meets an old woman who is also paralyzed but I'm pretty sure it's for a different reason. I never reached the end, but I think it was going to be tragic and/or controversial.
One more thing--I remember a detail about the sun shining through a window.

Skallagrig by William Horwood?
"Unites Arthur, a little boy abandoned many years ago in a grim hospital in northern England, with Esther, a radiantly intelligent young girl who is suffering from cerebral palsy, and with Daniel, an American computer-games genius. This book has been made into a BBC film."

I think it might be it, but in case it's not, I'm open to more suggestions. Thanks. :)

Never mind. I'm almost sure that's the right book. :D
