Review, Through the Looking Glass, June 1, 2010:
"This delightful picture book combines the traditions of Latin countries with those of Anglo Saxon ones bringing together the Tooth Fairy (who is English in origin) and El Raton Perez (who first appeared in a book in Spain in 1894.) Children who are about to lose a tooth will greatly enjoy this story about cooperation and friendship."

Review, School Library Journal:
"When Miguelito hides his lost tooth under his pillow, he has no idea that he is setting off a power struggle between the English-speaking world’s Tooth Fairy and her Spanish-speaking counterpart, El Ratón Pérez.... Young readers may not consciously recognize this tale as a metaphor for growing up in two cultures, but the story does model how to successfully negotiate a bicultural life... An excellent selection for libraries serving bicultural families."

"A marvelous story merging cultures seamlessly and with great humor. Adults will enjoy this read-aloud just as much as kids." —Sandra Cisneros, award-winning author of The House on Mango Street
