The ultimate battle
(Book)

Amy, Charlie and Sam -- three children from our world -- are bound by a powerful legacy. They are descendants of the Guardians of Avantia, an elite group of heroes. Now the time has come for a new generation to fulfil its destiny. The children face their greatest challenge yet as their Quest transports them magically to Avantia, home of their ancestors -- the original Guardians. There they meet the legendary Tom and Elenna themselves, but it's not long before a new battle ensues. Their old enemy, Illia Raven, is determined to control a Beast of her own, and will stop at nothing in her attempts to dominate the world.
