The Amelia Six is the story of six clever girls who are invited to spend a night in Amelia Earhart's home because of their achievements in STEM (specifically flying and aeronautics). Although all big-time Earhart fans, each of the girls are different. There's shy, anxious Amelia (Millie) whose mom left her to go be a pilot. Then there are twins Robin and Wren who run a YouTube channel, Thea who builds things, like the side car she arrives in with her aunt's motorcycle, Nathalie and her pet rat and Cassie whose parents work at NASA.
The best middle-grade mysteries to me are those that have more than just a mystery as the plot. But, I have to admit, many great middle-grade mystery books are also just about the mystery (at least it's the central plot) -- and that's fine too. For today's list, I've included the best middle-grade mysteries as well as a sprinkling of early readers (chapter books) aimed at younger readers. I've marked which ones are part of a series, so if your kids enjoy series, you can get your hands on those picks.
