The Doom Stone

A killer beast—half-man, half-apelike—terrorizes the English plain on which Stonehenge lies. Fifteen-year-old Jackson Cauley, with the help of his anthropologist aunt and a local girl, has tracked down the predator's lair. But the source of the beast's power lies in the ancient Doom Stone of Stonehenge, and unless its secret is unlocked, the deadly slaughter will continue.
