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.
While I was making this list, I thought deeply about what makes a "strong female protagonist" to me. None of the girls in these books are "perfect," obviously and they don't always do lovable things, but they will be scored on your heart by the last page. Even better, they'll leave you feeling you feeling inspired. You'll find fierce girls who play sports, are thrilled by science and space, solve mysteries, enjoy music, love hard, are loyal friends, courageous dream chasers, and wonderful daughters.
