This is a book for kids but was quite enjoyable. The narrator was great, the plot was sometimes intense. The writer did a great job. I am looking forward to more by Ms. Collins.

I didn't like the narration; a little too much lecture/professor. The ideas are interesting to consider. I am a believer unlike the author and therefore don't think that everything he said is fact. However, I enjoyed the explanations of scientific fact and his order of explanation was great.

Great narrator. I love this author. The premise of time travel is masterfully imagined and told in this book. I can't wait for Jack to write another.

I was stunned to listen to the author's findings. I hope that perhaps more of our educators and parents will read/listen to this book. The idea that we have created an environment which will or has changed our future men into future milktoasts is depressing. But, the author does give us ideas for change and room to hope.

I liked this book because it is fiction. The obviously impossible deeds of the hero/heroes made this entertaining and a great listen. Anyone who must have a 100% factually true fictional book is looking to the wrong genre IMHO. I enjoyed this book.

I enjoyed this book. The twists in the plot kept me guessing and made the listen enjoyable. I am ready for the next book from Mr. Lee.

Unexpected interaction between the Underland and Overland.

It is a new and unexpected world to imagine.

Great narrator.

Although it is a book for youth, it is quite enjoyable. I love the idea of a world under our feet: Underland. The imagined interaction between the Underland and the Overland is fun. A great narrator and great author. I am looking forward to the entire series and more books from Ms. Collins.

The beginning was unexpected in that you are completely immersed in the world with little introductory background (not much, if any backstory). Regardless, it forced me to pay attention to understand the interaction of the characters; a great way to trap me into a book! I am looking forward to listening to the other books in the series.

I was excited to listen to this book. The narration was so monotone with slurping, swallowing, and other similar noises that I only listened to the first 5 minutes, fast forwarded it to see if it improved and. . . It didn't. Don't get this.
