What an incredible read! It was an adventure until the end, with a fun twist on what you might expect to happen with the Cavern of Light. This book has themes of faith, community, team work, self discovery, mercy, the importance of honesty, and so much more. I was particularly impressed by the way Susan gave the opportunity for children to see that they have the capacity for both wisdom and what would typically be considered an "adult responsibility", and that the adults in the novel were capable of both remorse, understanding, apology and respect for the points of view of their children. It was a brilliant display of the truth of humanity, and what society could look like if we choose a path that focused on values rather than the pursuit of wealth and excess.
The character development, world building and imagery in this book were wonderful and painted a very real image in your mind as you journeyed through the pages. The folksy lore was reminiscent of some of my favourite childhood reads and blended what could easily pass as a historical version of the real world with magical elements. I would be beyond excited if this was ever picked up as for a screen adaptation. This might be middle grade fiction, but I think it could be enjoyed by all ages. I highly recommend this book. It has the capacity to be an instant classic in your collection. I know I can't wait to share it with my son.
