Publishers Weekly found the theme of Rangergirl simplistic and naïve. Kelly Shaw of Strange Horizons praised the first half of the book for its intriguing cast of characters, but criticized the latter half for its adherence to conventions of the Western genre and what he felt was "over-the-top characterization of the Outlaw." Kirkus Reviews also criticized the book's second half, calling it a "thin premise" that Pratt did not have the skill to maintain.
