I can see why this book has such polarized reviews. It is widely billed as Harry Potter, in college, for adults, and while that does accurately describe much of the setting there is so much more here to the actual plot. This book is primarily about the characters and takes an almost existential look at what do people become when they can have anything they want, whenever they want it. Maturity, growth, and the question of accountability are all central themes to the narrative and overshadow the standard epic fantasy aspects. This book works very well as a study of humanity framed by an interesting story. 
 The story also serves as an homage to all of the fantasy greats who have come before. There are plenty of nods to Rowling, Tolkien, Lewis, and many others. These nods provide gravity and levity to varied situations throughout the book, including a passage where a map is constructed on graph paper. 
 This book is well worth the read and all of the critical acclaim I've seen it receive. Just don't come expecting Harry Potter as a college student.
