2 min readSource

Explore the top 16 BookTok viral books 2025. From Alchemised to the latest Hunger Games prequel, discover how TikTok is reshaping the publishing world and bestseller lists.

The publishing industry doesn't run on traditional reviews anymore; it runs on hype. In 2025, the BookTok community has proven its absolute dominance by turning obscure 90s novels into chart-toppers and fanfics into literary phenomena. It's a year where the 'For You Page' dictates what ends up on your nightstand.

The BookTok viral books 2025 list: From fanfic to Booker Prize

You can't scroll through TikTok without hearing about Alchemised by SenLinYu. Originally a viral Harry Potter fanfic titled 'Manacled,' this dark fantasy hit the New York Times bestseller list immediately after its September 2025 release. Meanwhile, the literary world saw a collision of prestige and viral fame. David Szalay's Flesh, which won the 2025 Booker Prize, became a TikTok obsession after being picked for Dua Lipa's book club, making physical copies nearly impossible to find.

Resurrected classics and blockbuster franchises

Perhaps the most shocking entry on the 2025 list is Jacqueline Harpman's I Who Have Never Known Men. Despite being published in 1995, it became a global bestseller this year thanks to the algorithm's love for unsettling dystopias. Of course, big names still carry weight; Suzanne Collins' Sunrise on the Reaping and Rebecca Yarros' Onyx Storm fueled a binge-reading frenzy that dominated the second half of the year.
