There Be Demons by M. K. Theodoratus
Andor Demon Wars Book 1
Britt doesn't even dream demons exist. Then the Angeli draft her to fight them.
When the stone effigy she finds turns into a live gargoyle and tells her she must learn Magic or Grace to fight demons, headstrong Britt Kelly wants to run the other way. She has enough problems fitting into a new high school in the projects and coping with her parents' divorce, thank you.
Gillen, the centuries old leader of the Gargoyle Guardians, knows he has a serious problem — teaching Britt and her teenaged friends to control enough Grace to survive the coming battles against the invading demons.
Britt and Gillen soon fight over how to cope with the demons. Will anyone survive?
“The story contains action, adventure, and an intriguing new take on the age-old
theme of angels and demons.”
A personal message from the author:
“I wrote a short story Night for the Gargoyles in which I mention Britt Kelly, but I kept thinking about how Gillen and Britt would get along after I sole it. So, I wrote There Be Demons to find out. Try a sample chapter on Amazon. After all, Britt didn't even know demons existed at the beginning.”
