Martin de Porres: The Rose in the Desert, by Gary D. Schmidt and illustrated by David Diaz. 2012 Clarion Books
I just posted this on Amazon:
I read aloud a longer book about this saint to my 11 year old daughter last year Saint Martin de Porres, and it became her favorite saint. His humble origins, service oriented life and love for animals won her heart! We were pleased to find this beautiful picture book about the well-known and beloved Peruvian saint. Not all of the major facts of his life are in the book but there is enough in the story for the young reader to have an introduction to his life. Books on lives of the saints are very inspirational and greatly needed today!
