River Teeth is a journal of nonfiction narrative, and its book review section operates with a distinct editorial mandate: to attend to literary nonfiction issued by small, independent, and university presses—work that frequently escapes the notice of larger review venues. The journal seeks pitches that name a specific title and demonstrate familiarity with the author's broader body of work or the subgenre in which the book sits. This is not a venue for generalized appreciation; it is a space for situated, informed critical writing. The scope of eligible work is deliberately broad within the nonfiction field: memoir, the personal essay, literary journalism, and hybrid forms are all named as welcome. What unites them is the journal's commitment to narrative nonfiction as a literary practice. Reviewers are asked to write with the aim of recommending work they are genuinely excited about, though the review may be critical in part. The governing spirit is advocacy grounded in knowledge, not dismissal. Reviews run in the neighborhood of 1,000–1,200 words. There is no submission fee. The deadline for pitches and submissions is December 1, 2026. The journal notes that its publishing schedule extends well into the following year, so contributors should calibrate their expectations accordingly. Reviews must be human-generated; work written with AI assistance will not be considered.
