It's a LONG read, but well worth it.
Susanna Clarke is amazing when it comes to world building. The way she builds on English folklore and Fae is really intriguing. The only flaw is that, like I said, it is LONG, but truthfully I can't think of much of anything that could be taken out. Everything is so intentionally laid out and built upon. I will say having all three mediums (physical book, audiobook, ebook) helped to make it go by faster since I could keep going no matter what I was doing without lugging around this doorstop of a book.
