4,5/5. Good prequel to a great series. I read it after reading the first three books and I still enjoy it even if all the basic introduction to the world were a bit repetitive since I already knew most of it. It still can be read during the series, or start directly with it and you won’t be lost or bored in any way, and even if you don’t read it, you won’t be lost reading the others as well. So a good add-on to the series. A series that every fans, or future fans, of this series should read because it really worth it. Of course it’s a novella so it doesn’t have the depth of a novel, but there is still a good back story to this book on its own.
