Seanan McGuire's Beneath the Sugar Sky
I can already tell I’m gonna tear through these, both because they’re short and because they’re fun. This one involves the daughter of a character who died in book one, demanding they save her mother or else she’ll vanish bc the timelines are messed up. There's also a new student who’s a mermaid! (This was my only issue with the book—the character is fat and keeps dwelling on people being assholes to her about it, and worrying about other people being assholes other about it, and I wished there was a little less of that.) Very fun adventures otherwise. A-/B+.
