Shadow Castles Books in Order

After falling from Stirling Castle, dying Conall Canmore finds himself healed in an earlier version of the city. Repeated journeys backward through history unfold alongside a succession crisis and terrorist attacks in an alternative modern Scotland.

A second ghostly castle appears in Dalria’s capital, sending Artemis Macintyre and James Guthrie to find the key that might close it. Rival powers maneuver to control the anomalies while investigators pursue the forces behind the attacks.

Artemis Macintyre’s team can now predict the destructive course of the Shadow Castles, but stopping them remains elusive. As another threatens Dalria’s second city, evidence suggests an organized design and troubling questions surround Conall Canmore.

Facing the growing threat of the Shadow Castles, Dalria assembles a team to enter one. Their mission seeks to establish whether the anomalies are natural phenomena or weapons threatening the nation.
