Replying to Book Summary... HELP

Alright so for my English class we have to read On Beauty by Zadie Smith. Its like 450 pages long and I've supposed to be reading like 50 pages a night for the past week but I've been completely swamped with homework (I have finals next week and all my professors are cramming shit into this last week). So basically, I'm about 25 pages into it when i should be about 425. I've been searching all over the internet for a decent summary of the book but I can't find it (most likely because the book is really recent). Its probably a lost cause but I was just wondering if anyone knows of a website that might have a summary of this book (I already checked sparknotes and cliffsnotes and a few others). I would pay for it too so if any of you know of sites that sell summaries that would be prime. Again, its probably a long shot but I would really really appreciate it if anyone could give me any help. Thanks.
