Keeping 13 (2018) is a new adult romance novel by Chloe Walsh. It is the second novel in the Boys of Tommen series that follows the lives of several high school students growing up in the Irish city of Cork. Originally self-published by Walsh, the novel, as well as its prequel, Binding 13 (2018), gained popularity largely through video recommendations on the social media site TikTok. As a result, the novels were republished by Bloom Books in 2023, with several more novels in the Boys of Tommen series planned for future publication.
