This is a dark and weird story of some seriously messed-up youth. Gregorio, with his straightforward madness, is perhaps the most accessible of the characters. Delusions, depression, & suicide are comprehensible. The others, all sleeping with & cheating on each other, never apparently working, seldom going to school, laying about, lying to everyone, and, of course, constantly having sex with someone--these characters are harder to understand, yet not quite as much as the parents, teachers, and hotel owners who indulge them.
The inside cover and "advance praise" refer to this as a haunting, beautiful, etc. novel of love, passion, friendship & madness. And even though I can't really understand most of the characters, I suppose I must admit that I did find it haunting and I had trouble putting it down. The love, passion, madness, etc. operate on multiple levels, with the surface being only part of the story, perhaps the less important part. I would give more stars if I'd found the characters more sympathetic, less self-indulgent.
