Hasamba
 A group of girls and boys set up a secret society called "Hasamba"; their adventures take place, first during the British Mandate and the struggle for statehood of Israel, and then as they battle their country's enemies: infiltrators, spies, criminals and other offenders. The group has taken active part in the wars of Israel during the period the series has been written (until 1994). Though suspenseful, the writing is entertaining, with humor, as well as with related science, history, and trivia information, provided by knowledgeable participating characters. It emphasizes kindness, good behavior, loyalty, friendship, dedication, courage, and love to Israel. Yaron Zahavi (the handsome guy) and his deputy, Tamar (the pretty girl), are the first leaders of Hasamba. In later books (where they are supposed to be much older) they are replaced by the younger Yoav Tzur and his deputy, Rachel. The other heroes are replaced as well. Years later Yaron and Tamar get married, and their son Uri joins Hasamba in book number 25. In the books they face dangerous and smart enemies. They fight them, occasionally become captives, but outsmart the enemies and get free, sometimes with help of allies, and finally win. But not always a happy end: Two of the first-generation heroes, Eliahu Hermon and Refael Kaduri die, sacrificing their lives for important causes. Their secret meeting place is a real location in Tel Aviv, known as "The Electric Cave", which upon returning from a long stay abroad, the author discovered to be destroyed for the sake of building the Tel Aviv Hilton Hotel. High-tech inventions, sometimes preceding the technology available when written about, plays role in the stories. This includes the Electric cave, an intelligent robot, "Zagloba," that helps the group in some adventures, a laser rifle, and more (Yigal Mossinson himself was the inventor of patents).
