This Narnia novel is set mostly in Calormen, Archenland and Narnia during the golden age of the High King Peter. A young boy named Shasta lives a harsh life with a fisherman who is not his true father. When he learns he is to be sold, he escapes with a talking horse, Bree, who was also taken from Narnia. Along the way they meet a proud young noblewoman, Aravis, and her horse. Together they journey north across the desert, hoping to reach freedom. It is an adventure about courage, identity and belonging, and it shows a wider world beyond Narnia.
