"The story succeeds as both a philosophical dialogue and a classic tale of bedtime delaying tactics. . . Marshall Yarbrough’s charming translation from the German shines, especially in the — plot twist! — excellent backmatter, which discusses the original rhinoceros debate and explains what philosophers do."

– Mac Barnett, The New York Times

"Ludwig’s childlike faith in his rhinoceros will ring true for young ­believers and ­imaginers everywhere. Three-color ­illustrations in a palette recalling that of Goodnight Moon create a vibrant nighttime landscape."

– School Library Journal

"Giving little ones—Ludwig and readers—the power of owning the book’s perspective is an interesting flip of traditional adult-child dynamics. Here, the child holds the knowledge that the adult struggles to understand. "

"Blues and greens contrast with neon yellow and fiery orange in this philosophical bedtime story that tackles the rhinoceros in the room."

– Foreword Reviews

"The day-glow illustrations by Golden Cosmos fit the surreal storyline perfectly, and include plenty of humorous moments that will keep kids engaged and giggling, along with the fact that kids will be cheering for the victorious Ludwig. The front and back end papers, both different and engaging, add another layer of personality to an already sweet, but elusive rhino."
