This is a delightful book for the Middle-Grade age group. Donna uses animals to embody and portray positive actions and affirmations for young people-such as resilience, courage, friendship, (including befriending those who are different), honesty, loyalty, and perseverance. The characters are great and easy to identify with. The plucky Simon Cheddar is a survivor and passes on knowledge and helpful advice to those who are around him. He is loyal, devoted and never gives up, even in the face of losing family members and friends. He stands by his new friend Catt when she is in terrible trouble. Patty the pig is an out-there character who also never gives up, determined to help wherever she can with her super-techno skills. She is ably assisted by Freddy the frog. This diverse group of friends finds themselves attending Superhero school, but the tutor is anonymous. Will they ever find out the identity of the one giving the lessons? Have they been thrust into real-life superhero work before they finish their schooling? Let the reader decide.
