It's The 100 Day 21
By Kaylee V.
The 100 Day 21 is a perfect sequel from the 4 book series by Kass Morgan. Kass Morgan isn't a well known author, her first book being the beginning of The 100 book series. The book itself became so popular it became a well known televised show on The CW. The show already working on it's 5th season (possibility of a 5th book). A lot of questions were stirring after the ending of the first book, every single one addressed. Though at the end of this book more and more questions arise.
The main question was the major cliffhanger at the end of the series, they weren't alone on the ground. The delinquent teens thought it was just themselves on the radioactive earth but it turned out people must've survived the catalyst. It didn't seem as if the 'grounders' were friendly, our first encounter with them was a brutal murder of Asher (one of the tougher boys from the Ark). Another question still remained, where is Octavia? This question also goes along with the new conflict with the grounders. As the story progresses we learn that the grounders are split up. Some believe that the newly arrived Arkanians are friends while the other group visualize them as foe. The small group of angry grounders take one life and kidnap another.
Back on the failing Ark more and more conflict emerges. We get more background on Luke and Glass's history and even a heart wrenching confession that may cost them their relationship.
Like any good book series after the ending of one there's always a question needing to be answered. In this case we're all waiting to see what happens when the Ark comes to the ground. Though since 2 more books have officially been released you can find out yourself just what happens to our favorite characters and how they might interact with their new challenges.
