Forced to become mortal, ex-teen angel Griffin has been banished from the Terrae Angeli. Struggling to adjust, he enrolls in the heaven-and-hell known as high school. In spite of his friends’ support, Centennial High proves to be a battleground, complete with a malicious math teacher.

And to make matters worse, his Mentor, Basil, has been ordered to take on a new apprentice, the gifted and egotistical seventeen-year-old Sergei, whose covert attacks make Griffin’s home life as bleak as a Siberian winter.

Caught between school, Sergei, and a desperate secret, Griffin is certain of one thing: the only way to fight a Cold War is with Fire.

Finnegan MacCullen - a thirteen-year-old apprentice with the famous Irish temperament.
Gideon Lir - a legendary Celtic warrior with a bit of a temper of his own.

Secretly, these blue collar warriors battle the hobgoblins infesting their suburban neighborhood.
When they're not battling each other.

Finn (not bleedin Finnegan) MacCullen is eager to begin his apprenticeship. He soon discovers the ups and downs of hunting monsters in a suburban neighborhood under the demanding tutelage of the Knight, Gideon Lir. Both master and apprentice are descendents of the Tuatha De Danaan, a magical race of warriors fromIreland. Scattered long ago to the four corners of the world, the De Danaan wage a two thousand year old clandestine battle with their ancient enemy, the Amandán, a breed of goblin-like creatures.

Now with the beasts concentrating their attacks on Finn, he and his master must race to locate the lost Spear of the Tuatha De Danaan, the only weapon that can destroy the Amandán, all the while hiding his true identity from his new friends, Rafe and Savannah, twins whose South African roots may hold a key to Finn’s survival.

Armed with a bronze dagger, some ancient Celtic magic, and a hair-trigger temper, Finn is about to show his enemies the true meaning of "fighting Irish."
