Chronicles of the Red King: The Secret Kingdom

Timoken is a prince born in a secret kingdom. At his birth, a forest jinni bestows magical gifts upon him: a cloak made by the last moon spider and a potion called Alixir. When the peaceful land is attacked, Timoken and his sister, Zobayda, must find a new kingdom to call home. Together, with only the magical gifts and a talking camel, the siblings set off.
