"Sedgwick’s story and Taylor’s images work well together to create an immersive experience... Young readers will find Scarlett aspirational. She’s brave, but not unafraid. She’s bold, but not arrogant." —New York Times

"The weapons, gadgets, catchphrases, and nondescript Victorian setting will appeal to fans of the steampunk genre, [Scarlett Hart] will likely appeal to comic fans as a bridge between Scooby-Doo! and Paul Pope’s “Battling Boy.”"—School Library Journal


"A cliff-hanger ending, along with a handful of secrets about Scarlett’s parents left unexplained, hopefully means there’s a sequel yet to come. This solid middle-grade caper is perfect for fans of Jason Segel and Kirsten Miller’s Nightmares! series."—Booklist

"Monster hunt after monster hunt keeps the story whizzing along nicely, with plot developments and revelations sprinkled throughout in a rollicking manner. Rough and scrappy, Taylor's illustrations convey ghoulish cool with subtle aplomb..."—Kirkus


"Sedgwick and Taylor’s story unfolds in lively action sequences, and the banter between Scarlett and Napoleon provides humorous interludes."—Publishers Weekly
