The Caledonia Regression (Shadow Castles)

By Tormod Cockburn

The ancient walls of Stirling Castle hold many secrets. But none has ever been as dangerous as this.

After an assassination tears apart Dalria's royal family, Artemis Macintyre and Major James Guthrie discover a mysterious fortress erupting through the castle walls-and inside it, a dark, smoky curtain flowing like a waterfall.
When they make the fateful decision to cross, they experience the impossible sensation of falling while their feet remain firmly on the ground. Falling through space, or through time?
Meanwhile, in another Scotland, elderly stonemason Conall Canmore wakes decades in the past, young again and inhabiting the body of one of his ancestors. Soon he discovers he is not alone. Others are being thrown backwards through their family lines, carrying memories of futures that have not yet happened.
As the mysteries begin to connect, one terrifying possibility emerges.
Could the greatest threat to Dalria's future already be lurking in its past?
