This is a verbal review from both a third and sixth grader who completed the book - as a disclaimer, I did not but then again a middle-aged gray-haired guy is not the target audience!
This is the sequel to The Golden Acorn, which should be read first. Bottom line summary is they both the 3rd and 6th grader loved this book, and they were both quite insistent on purchasing the Kindle-format sequel to the Golden Acorn. When asked what they liked the most, the third grader said he liked the characters, time travel, and the story, which was about all I could get out of him. The sixth grader said she liked the fantasy / science fiction aspects as they are her favorite genres, and she really liked the alternate reality travel aspect. Both of them said they would recommend it to their friends, and three friends downloaded both the Golden Acorn and this sequel to their Kindles.
Similar to the experiences with the Golden Acorn, after reading this book the sixth grader carried on a conversation of how neat it would be to have something like the golden acorn in real life, what she would do, etc. until I couldn't take it anymore.
As I type this, the Kindle price is $1.04 - I believe this is one heck of a bargain and obviously something you should grab for this summer to keep your kids a little occupied: where else can you spend just $1.04 and have both kids entertained for several hours? What I really like is it appears to be a great story and having them want to read more and exercise their minds vs. playing an endless video game!
