No one has set foot on Earth in centuries — until now.
It’s been 21 days since the hundred landed on Earth. They’re the only humans to set foot on the planet in centuries…or so they thought. Facing an unknown enemy, Wells attempts to keep the group together. Clarke strikes out for Mount Weather, in search of other Colonists, while Bellamy is determined to rescue his sister, no matter the cost. And back on the ship, Glass faces an unthinkable choice between the love of her life and life itself.
In this pulse-pounding sequel to Kass Morgan’s The 100, secrets are revealed, beliefs are challenged, and relationships are tested. And the hundred will struggle to survive the only way they can — together.


I jumped right into Day 21 immediately after finishing the first book in this series, The 100. This book picks up shortly after the first leaves off, with the 100 realizing that they are not the only people on Earth as they originally thought. I still enjoyed this book immensely, but found a few flaws in it.

First, the writing felt a bit watered down to me in this second book. I loved how rich the writing is in The 100, but Day 21 feels like it was adjusted for a younger audience. I also found two continuity issues in this book, which detracted from my overall rating. For example, in Day 21 Clarke mentions that the only mammal she’s ever seen before is a deer, but in The 100 Clarke saw a rabbit. These continuity issues were very small, but still quite noticeable, especially when reading the books back to back.

Similarly, Day 21 was much more predictable than the first book. I found that a bit disappointing, but thankfully was still wowed at the end of the novel. Morgan tied everything together once again, and I found myself on the edge of my seat. What I really love about this series is how addicting the books are. Because we follow four characters, I am constantly turning pages to find out what will happen next. The twists and turns are my favorite part, and I wish I wasn’t able to predict many of the moments in the book.

My final critique of Day 21 is the back and forth moments of some of the characters. For example, Clarke can’t seem to decide whether or not she wants to forgive Wells and be friends with him. One minute she hates Wells and never wants to see him again, while the next Clarke forgives him. This got a bit annoying, especially when Bellamy goes through a similar battle later in the book. He jumps to a conclusion really quickly, just to change his mind a moment later.

Nonetheless, I still really enjoyed this book and am ready to pick up the third book in the series. While Day 21 is more of a 3.5 star rating, I bumped it up to a 4 because I love it so much. The cliffhanger ending is just amazing, even though I did see it coming. If you read The 100, I highly recommend continuing on with the series. You’ll want to see what goes down in this book for sure!
