This is the third book of the Chronicles of Narnia series and is about a boy, called Shasta, who was looked after by Arsheesh,
a Calormene fisherman. After many years, Shasta was going to be sold as a slave to a rich
noble man so he decided to run away with, Bree, a talking horse belonging to the noble man, to Narnia. On their travels, Shasta and Bree meet Aravis, and her talking horse, Hwin. Together they
travel to Narnia but the four have to travel through Tashbaan, the bustling capital city of Calormen. There Shasta is mistaken for Corin, the prince of this city who is actually his twin but that is not known by him. At the end, Corin’s father realises that they are twins and Aravis lives at the palace with them later on getting married to Cor (Shasta’s real name).
