Note that this is part of a trilogy that hasn't had the third book released and its been 10 years. I doubt it will be out in another 10, so tread with caution if you don't like to wait on a book release. Amazing book though.
I've read (or listened to) this book maybe five times. Maybe for a bit of context for someone who's not that into fantasy fiction. The crazy thing about it is that is the basic story is the most standard wizard book ever. It borrows more than a little bit from the classic Wizard of Earthsea for example.
But Rothfuss just takes every one of those tropes and wires them together into absolute riveting story telling. He basically perfects the genre.
If it takes another 5 years for the last book to be released, I might just take up fantasy writing myself and come up with an ending for it, I guess it invites the reader into the field that way..
