★ "Lehman’s watercolor, gouache, and ink illustrations are clear, warm and inviting. Varying panel sizes and perspectives pace the story, drawing attention to the narrative’s subtle complexity. The almost-all-red cover echoes the characters’ own red books, affording readers an opportunity to ponder the story’s mystery and their potential connections to it." --The Horn Book, starred review

★ "This title stands alone but pairing it with the first work makes it all the more magical, particularly because the end brings the story into a breathtaking circle... Whether being explored for pleasure or for academic purposes, this title will add value to any library collection, especially ones that have copies of its predecessor." –School Library Journal, starred review

★ "Lehman gives readers the satisfaction of learning more about the original story while leaving them with more to ponder. Together, the two volumes form a pleasing and perplexing Möbius strip of a story." –Publishers Weekly, starred review

★ "... A twist ending that will blow many young minds (and some not-so-young ones, as well). " –Booklist, starred review

"A peaceful, wordless adventure that, as the final frames hint, will continue after it's closed." —Kirkus
