mouse started reading Nona the Ninth by Tamsyn Muir (The Locked Tomb, #3)
Each book in this series seems to get me interested enough in a character and then end with a lot of cliffhangers which don't get addressed for another 600 pages while the story does something completely different and I'm coming into this one grumpy about having to care about completely different people while getting cryptic allusions to the previous characters' fates
