Project X Hero Academy is a fully decodable and finely levelled reading series set in a school for superheroes, designed to captivate and motivate all young readers and turn them into reading superheroes. The Mysterious Miss Tula is in Lime Book Band, Oxford Level 11. In this story, a new librarian joins Hero Academy. But Evan thinks there's something strange about her. Who is she, and what does she want? Each book can be used for independent reading, but also contains inside cover notes that include help on developing vocabulary and prompt questions that can be used for guided reading and one-to-one sessions. Full guided reading notes are provided in the corresponding handbook. There are also a range of follow-up activities to support reading for pleasure.
