100 Most Popular BookTok and Bookstagram Books

What readers are sharing now

Social reading moves faster than a traditional bestseller list. A new release can dominate reaction videos for a week, while an older paperback can return years later because one scene, trope, or quote catches fire. This top 100 brings those two kinds of popularity together: the established books that still define BookTok and Bookstagram, and the newer releases driving the current conversation. The result ranges from romantasy and contemporary romance to horror, literary fiction, memoir, thrillers, and science fiction.
