Such a great “conclusion” to the den of shadows series. I‘m pretty sure I‘ve read this at most twice before and I had forgotten how much I loved this. One thing about Atwater-Rhodes YA series (which all take place in the same world) that I love is the cameos. Characters that were mentioned passingly in one book become main characters a couple books later or in a different series. Antagonists become protagonists and vice versa. Love it.
