Okay. So you know there are a ton of books out there. Some have mentions about, say, fashion or cooking or gardening... Whatever you can think of, there's probably a book that goes around those topics. This list is for BFFL's. Best Friends For Life. If you can think of any book that the main characters have bffl's, well, why not put them down on this list? Maybe they've got that kind of friendship that you can insult them... Meaning well, of course. Or, what about drifting apart and then becoming closer than ever? This is BFFL... Best Friends For Life. ;)
