Possible Sequel Series Hint
At the end of the story in the Epilogue Percival had finished making a map of the Valley as He, Abbey, Barclay, and Randolf were exploring around the valley but then he is greeted by Ted the bug who said that they knew he would come as Percival questions who Ted reveals it was Norman and Emmy Bone, he then gets in control of the Queen as he sets out to find them.
Reasons why this could be a hint for a sequel, well for one thing in the Quest for the Spark book 1 we see that Percival was originally on a mission to find Barclay and Abbey's parents, in which they get sidetracked when they meet Tom and become apart of the Quest for the spark, so it means they could return to their old mission in perhaps another book or book series.
