Reach for this book when your child is struggling with rigid thinking about people they do not like or is facing a situation where they must collaborate with a difficult peer. While it is a fast paced fantasy adventure, the heart of the story lies in the complicated necessity of making peace with an enemy to solve a larger crisis. It provides a safe, metaphorical space to discuss the nuances of trust and the idea that people are rarely purely good or purely evil. In this installment of the Droon series, Eric and his friends face the return of the villainous Ko, who has seized a powerful submarine. To save Jaffa City, the heroes must do the unthinkable: team up with their long time nemesis, Lord Sparr. This story is perfect for children aged 7 to 10 who enjoy high stakes action but are ready to explore deeper emotional themes like redemption and the grey areas of interpersonal relationships.

This is a series book; if read cold, parents may want to explain that Lord Sparr has traditionally been the 'Voldemort' of this world, making this alliance a very big deal. No specific scenes require censoring, but the 'lightning submarine' sequences are intense. A parent might choose this after hearing their child say, 'I'm never talking to him again,' or observing a playground dispute where a child refuses to work with someone they've labeled as 'mean.'
Younger readers (7-8) will focus on the cool submarine and the scary monsters. Older readers (9-10) will pick up on the nuance of Sparr's character and the difficulty of the protagonists' decision to trust him.
