River Teeth: A Journal of Nonfiction Narrative has long served as a home for writing that treats fact with the seriousness of art. Its book review section extends that mandate to criticism: the journal seeks reviews that situate a single title within the author's body of work and the wider subgenre it inhabits. The scope is deliberately narrow in publisher and broad in form—memoir, essays, literary journalism, and hybrid nonfiction are all eligible, provided the book carries the imprint of a small, independent, or university press. This is not a venue for reviewing the season's major trade releases; it is a venue for attending to work that might otherwise go unnoticed by the review pages. What the journal offers is editorial space and a readership already invested in the nonfiction narrative tradition. There is no submission fee. Reviews are expected to run in the neighborhood of 1,000–1,200 words. The editors are candid that their publishing schedule runs well into the following year, so contributors should calibrate their expectations accordingly. The review may be critical, but the governing impulse is recommendation: the editors want writing that shines a light on a book the reviewer is genuinely excited to put before readers. The curatorial vision is one of informed advocacy rather than detached appraisal. A successful pitch names a specific title and demonstrates familiarity with the author's prior work or the subgenre in which the book sits. Reviews must be human-generated; the journal states plainly that AI-assisted work is not acceptable. In an era of algorithmic book commentary, River Teeth is asking for the thing only a committed reader can supply: a considered, personal, and knowledgeable case for a book worth reading.
