The Return of the Arch-Druid

He came back from Avalon. Edinburgh is still standing. Barely.

Nechtan "Cam" Cameron survived the Hollowing once - at a cost written across everyone he loved. Now he's home, and the fraying has started again: thin places tearing open across the city, and something wearing the Hollowing's name learning to wear other names too.

Then he finds the boy.

Fifteen-year-old Callum MacKenzie holds the same wild, godlike power that once burned in Caoimhe - power no one taught him and no one can take from him. Alone, he's a catastrophe waiting for a postcode. With Cam, he might become something else: the first student of a new Milton Street, a new-found family built from the wreckage of the old.

But the Hollowing remembers Cam. And it hasn't come alone this time - a spy walks beside them wearing the face of help, straight from the Isle of Skye, and not even Merlin's grand designs may survive what's coming.

The Return of the Arch-Druid continues The Nechtan Cameron Chronicles - where Holmes meets the old gods, and the price of magick always comes due.
