My granddaughter had told me about these books and asked me to read the 1st in the series, which I did while visiting them on vacation this summer. She said there were several more in the series she would like to have. I went to the library and ordered book 2 and 3.
I find this book series to be very interesting in the idea and content. A group of teens/children on their own in the blue time combating evil. I found the books very entertaining and had trouble putting them down.
I recomend this series to teens 13 and older.
