It's less Harry Potter for grown-ups and more: what if a messed-up kid who was a big fan of fantasy books was let into a Wizarding collegiate somewhere in Upstate New York and eventually found their way into a dark, corrupted version of Narnia.

Definitely recommended for people who waited and never received their invitations to Narnia or Hogwarts, and maybe got a little jaded as they grew up.

It's been a very long time since I've read a book that's demanded I read the entire series at once!
