I really liked this book, the writing, plot, and characters were all brilliant. Though, if this was a star rating, I'd still give it only 4 out of 5 stars. Simply because it did have a few slow parts that dragged on. Plus, there were a few plot issues that could have been buttoned up a bit more.
Overall, if you like RPG-lit or something with a similar premise to Ready Player 1 (Without the 80's lore) this would be a great book to pick up!
