The Ring of Gyges (The First Trilogy of 'Guardianquest' Book 2)

Peter is about to embark on a series of TESTS, set by the Elves, which may, or may not lead to his being apprenticed to Anir, the Guardian of Arx Emain.

Imperator Arthur of the Britons is fighting Goths in Roman Gaul, in the 490’s A.D. His desperate need for an invisible spy brings together; not only Peter, Merlin, Anir and Arthur, but also Sarah and Aunt Myf, who with the aid of the Ring of Gyges, join in this great adventure.
