They Bloom at Night by Trang Thanh Tran
This is a weird one, and I mean stylistically - it's incredibly overwritten, with some very intrusive phrasings that don't sound like people speak or narrate; plus, many of the characters infodump in a "verbatim from wikipedia" way (that actually feels like maybe that's what really happened, as in some cases it reads like the author doesn't understand the sentence they based the infodump on).
Eco/body horror with some twists, and a lot of levening with modern YA self-identity finding.
