Skellig, by David AlmondRead about the other entries on the list.
There have been so many high-concept sitcoms about normal people trying to keep some extraordinary creature hidden from the neighbors or the authorities—an alien on ALF, an alien on American Dad, a robot on Small Wonder, a genie on I Dream of Jeannie, and so on. Just sub in “wise and mystical human/owl/angel creature” for alien, robot, or genie and you’ve got Skellig!, the hilarious tale of a little boy who keeps his garage friend a secret.
