This is a book about a pair of identical twin teenagers who have virtually absent parents.
Good book, but a little dark. These are some seriously psychologically messed-up twins. Which I don't think is indicated by the cutesy-pootsey cover above.
The cover of the copy I read was better.>>>>>>>
Although I guess that cover wasn't particularly psychologically messed-up either.
It's just prettier.
