Yup, as a work of fiction (many authors use their own backgrounds and friends' backgrounds as fodder for the writing journey) it is awesome. Very beautiful and disturbing piece of work.

Passing it off as an autobiography is simply weak.

My Friend Leonard (the sequel) is also brilliantly written. As a fictional story.

I admire his writing talent, but my cynical side says that he promoted his books as autobiographical to make sure of sales.
