Of all the parents-with-mental-disorders teen books out there, this is the first I've seen dealing with obsessive-compulsive hoarding. I'd have liked to have seen more of the "before"--the daily life with the hoarding--and maybe even some of what happens after the ending, but the couple of days in the middle--all we see in this book--are still engrossing. 
 It's not quite right for fans of the super-dysfunctional families (a la Hopkins' Identical or David Pelzer's books) but those looking for a drama will probably enjoy this one.
