The annual TikTok Book Awards were held tonight in London, and the award for international book of the year went to Fourth Wing, a fantasy novel by U.S. author Rebecca Yarros. The book went viral on TikTok, which helped propel it to No. Yarros acknowledged the TikTok push in a video message: “It has been a wild ride, and none of it would have happened without TikTok! Huge love to the #BookTok community.”The winners were voted for by the #BookTok community on the video-sharing app. In other categories, Lisa Jewell’s None of This Is True was named book of the year.
