Mary Pope Osborne has a monopoly on 2nd-grade attention spans for a reason. These aren't the books that will change your life as an adult, but for a kid, they’re a rite of passage. They’re fast, they’re adventurous, and they make history feel like a playground instead of a museum.
While the original series can feel a bit thin for older readers, the Merlin Missions add enough depth and mystery to keep 3rd and 4th graders hooked. It’s the ultimate antidote to the 'I hate reading' phase and a much better use of time than an afternoon of brain-numbing YouTube shorts.
