Mr Kazarian, alien librarianPack A

Four quirky kids, one extraterrestrial cat and the world's best librarian team up to keep a secret of intergalactic proportions: Mr Kazarian (the world's best librarian) also happens to be an alien.

His important research mission to study the peculiar behaviour of young humans is at stake.

Trips to space, actual non-fiction science lessons and mysteries keep this team (and readers!) on their toes as they protect Mr K.'s identity and give him lots more human high jinks to observe during their adventures!
