Denizen Hardiwick is a smallish thirteen year old lad in Crosscaper Orphanage. He is not aware of having any relatives, but a couple of strangers take an altogether sinister interest in him. One day he is given a message to pack a bag and be ready to be picked up by his aunt. So begins KNIGHTS OF THE BORROWED DARK by Dave Rudden, which admits to a formulaic hero at the outset. The location however is Ireland; to be specific, the westernmost parish. What could go wrong?

Denizen is collected by a driver and taken from Achill to the outskirts of Dublin, but unexpectedly a tunnel collapses, trapping them on the road, and a huge winged beast stalks them. That's when the driver pulls out a sword. Clearly all is not as it seems. Meanwhile back at Crosscaper, Simon, best friend of Denizen, who enjoys reading crime stories and misses his pal, sees the strange couple collecting another boy at the gates. Having survived the attack, Denizen is taken to the embassy of the tiny land of Adumbral in the posh part of Dublin. Now he might get some answers from the woman who is allegedly his aunt.

Be prepared for explanations that don't explain anything, terms like Tenebra, Malleus and Obscura, the Higher Cant, swords, creepy clockwork women eating lightbulbs, an uneasy juxtaposition of the modern and the occult. The tale reminds me a lot of STONE HEART by Charlie Fletcher, set in London, except that Denizen has adults around, and clarifications take longer. Naturally the battle Denizen is now embroiled in has been ongoing for centuries, and he is now considered old enough to learn to fight.
