This book was so batshit insane and astonishingly wonderful. As is par for the course for The Locked Tomb, it was incredibly confusing but also stunningly executed. The work with POV in this book is great, using third, second, and first person in a way that hints at some situations revealed towards the end, and also making Harrow an unreliable narrator, making the reader doubt even the things that would usually be taken as fact. The mysteries of Lyctorhood are far from revealed, and the revelations in the latter third of this book completely blew me away. Looking back, a good majority of this new information is foreshadowed, and it's just so well-written. If I hadn't promised myself I'd be alternating between this and The Poppy War trilogy, I'd be picking up Nona the Ninth right now.
