InCryptid - Series by Seanan McGuire
The Covenant of St. George was founded to uphold one simple ideal: anything that was not present on the Ark—anything they deemed "unnatural"—needed to be destroyed. Monsters. Creatures of myth and legend. All of them would be wiped from the Earth in the name of Man's dominion. Unfortunately for them, not all the monsters agreed with this plan...and neither did all the human beings.
After their rather abrupt departure from the Covenant, Alexander and Enid Healy found themselves alone in the world, but with a simple mission of their own: to protect the cryptids of the world from those who would harm them without just cause. It was a cause that would eventually claim both their lives, leaving their children, and their childrens' children, to take up the fight. Now in the modern day, their descendants struggle to stay beneath the Covenant's radar, while defending the cryptids from humanity—and humanity from the cryptids.
