Some see them as friends, family even, but others see them as nothing more than dangerous beasts that the world is better without. Mac, Ping, Ava, and their keepers are in search of Mac's father who vanished one day and never returned. A heartfelt fantasy adventure from the writer of The Wild Cosmos, with luscious art by powerhouse Jo Mi-Gyeong, artist of Eve and The Dark Crystal.
