I spend HOURS reading these as a kid
(hexbear.net)
Fuck iPads, having kids look at glossy pieces of paper with diagrams of castles and pictures of cool pirate swords is what the children need.
my first library overdue fine was the viking one
i also had one about reptiles and one about mammals. maybe different book series but same style. i still have the mammal family tree etched into my brain, elephants, manatees and some african mountain rabbit belong together (guess the science changed since then though)
