But the thing I hated most was how it tries so hard to remind the reader that it's a completely different story than Harry Potter. I'm fairly certain that the fact that the title does not include the phrase "Harry Potter and the" made it clear to whoever picked it up that it was not part of the HP series. But the HP series is constantly referenced and it gets old fast.
But if you like existential novels, then you'll probably really enjoy The Magicians. There's also a sequel coming out this summer, so there'll be more opportunities to discuss how pointless life is. Huzzah!
