American Brandon Sanderson (Lincoln, 1975) is one of the best-selling fantasy and science fiction authors in the world. His youth series 'Alcatraz' began in 2007 with 'Alcatraz against the evil librarians', which we can listen to here (by clicking on the central image) in the audiobook read by David Jenner, in a fragment of a work that lasts a total of 7 hours.
The action of this first installment begins when, on his thirteenth birthday, the orphan Alcatraz Smedry receives a curious package: a bag of sand, an inheritance from his parents, who are missing. The bag is immediately stolen, and then Alcatraz understands that this is not just any arena. With it, the Evil Librarians, who secretly control some of the most powerful countries in the world, will also be able to control some of the Free Kingdoms. Alcatraz and a group of peculiar boys will be in charge of fighting them.
