Very different kind of book. In most books, things happen. This book discards that trope. “You expect things to happen in a book? Well in this book, it does not. Discuss!” And so for 252 pages, absolutely nothing happens. Risky? Perhaps. But it is undoubtedly novel.
This book was a bit similar to Watcher in the Woods, with different dimensions, but with a time travel twist. I liked it a lot, and I liked the ending, as opposed to WITW
