Can anyone recommend books for my 13 yo son with Aspergers syndrome?

He is a very high functioning, wonderful, funny child with an autism spectrum d/o who is just gaining an awareness of his disability and how he is different from his peers. All the books out there seem to be geared toward parents/caretakers or portraying the child with ASD as a victim. I'm looking for something more empowering! Any ideas would be greatly appreciated! :))
