Thunderboots [PDF ebook] 

Trixie is the smallest person in Primrose Tower, but also the loudest and the building’s residents have given her an affectionate nickname: THUNDERBOOTS. When it’s time for Trixie to start school, she is very excited. Sometimes it’s hard to concentrate in class, though. And it’s really hard to read letters. Maybe what Trixie needs is a superpowered plan. An empowering story about starting school with dyslexia that celebrates everyone’s differences.
