The Raven Tower

This novel takes some of its setup from a very famous and well-know- work - but it adds in a lot of fantastical worldbuilding and doesn't necessarily go where the reader might expect it to.

I think that it's a very good novel, and really skilfully-written. I admire the craft in it, but I did not love it. I had also figured out a fair bit of the ending's revelations well before the end, which possibly diminished some of its effect for me. It's more than a bit dark, but it's terribly interesting, and I do recommend reading it.
