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. And, to make matters worse, his Mentor, Basil, has been forced to take on a new apprentice, the gifted and egoistical seventeen-year-old Sergei, whose covert attacks makes 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.
