Young adult novels are in for the end of 2025 - just ask BookTok. Maybe you preordered the next Lightlark novel, Crowntide, eons ago - or have never even heard of author Alex Aster (who's great, by the way). But there are several YA book series on Us Weekly's ever-growing TBR pile, and while we're sad that some of them are coming to an end, it just wouldn't be fair to gatekeep these titles.
