Guardians of the Tall Stones — Moyra Caldecott

Fourteen-year-old Kyra has always felt different, but lately even her brother Karne has noticed her acting strangely--especially when she's near the ceremonial sacred stones that help guide and protect her village. When the villainous priest, Wardyke, overthrows the beloved elder, Maal, and threatens them all, Kyra must accept that her emerging psychic powers are her people's only hope. With guidance from Maal, and help from Karne and her best friend, Fern, Kyra enters the forbidden circle of stones to call upon unseen, mystical powers to banish Wardyke once and for all!

Moyra Caldecott's The Sacred Stones series, set in Bronze Age Britain, introduces readers to a time when magic existed in the workings of everyday life and the threat of evil loomed in the shadows.
