Celebrate Yalda Night with the Yalda Book Series Celebrate your Yalda Night with the Yalda Book Series (Iliya and Yalda, Yekta and Yalda), designed to teach the beautiful Persian language to children. These books were created by Dr. Noushan Ashtari (a linguist and university professor) and Engineer Behnoosh Ashtari (an architect and digital designer). The goal of the Yekta/Iliya Adventures and Iran series is to familiarize Iranian children living abroad with the Persian language and Iranian culture. Other books in this collection, such as "Iliya/Yekta and the Alphabet" and "Iliya/Yekta and Nowruz," are coming soon.
