The Lion King meets Wings of Fire in the magical rainforest kingdom of Caldera in this new middle grade animal fantasy series from New York Times bestselling author and National Book Award finalist Eliot Schrefer.

Caldera has forever been divided into those animals who walk by night and those who walk by day. Nightwalker panthers, like young Mez and her beloved sister, have always feared daywalkers as creatures of myth and legend. Until the eclipse.

Now Mez has discovered that she can cross the Veil and enter the daylight world. Her magical power has unknown depths, but she must rush to discover it after a mysterious stranger arrives at her family’s den, bearing warnings of a reawakened evil.

Saving Caldera means Mez must leave her sister behind and unite an unlikely group of animal friends to unravel an ancient mystery and protect their rainforest home.

    Did you ever read “The One and Only Ivan” and really wanted a sequel? Maybe this isn’t a sequel - but it’s definetley amazing and similar to it! Adventure through the jungles that Mez, a young panther - experiences with magical powers to discover! This book actually made me cry (hint: a small, sad part of Mez’s sister and leaving her behind because she lost one of her paws). This is a great book recommended, you should DEF-IN-IT-LEY read this!

          Oh my gosh! This book is so funny. I didn't expect it to be as funny as it was. I thought it would be a really compelling fantasy story, but It made me laugh out loud so many times that my mom kept asking what was happening and we ended up reading it together.

              This book was full of secret fun facts, exotic animals, and spine tingling adventure! I totally recommend this book, only if you like crazy twists though. This is a good book to choose a favorite character, and I loved how it was so described, you could play it out in your mind! I really loved this book and I wish good luck to all those reading it! Also, anyone with a strong love of animals should TOTALLY read this book! :D HAPPY READING!!!

                  I don't really like this book. It wasn't written well and I didn't care for the storyline. It is about a black panther (not from Marvel) named Mez who should be asleep during the daytime. Animals in the rainforest are separated from ones who walk at night and the ones that walk at daytime. She isn't asleep so she looks out her cave and sees a snake. And snakes walk at night. I don't recommend this book.

                    Mez is a black panther who lives in a rain forest named Caldera. The rain forest is split into the nightwalkers and the daywalkers. Between that is called the Veil. When a solar eclipse happens, Mez joins together with some of the solar eclipse animals.

                      This book is really captivating. It's about a black panther named Mez who lives in the rainforest called Caldera. Caldera's animals are split into 2 categories. Those who live at night and those who live at day. The time in between is called the Veil, and to cross it makes you an unnatural. But there are some animals born during the eclipse that have magical powers and are able to cross the veil. Mez joins together with other eclipse-born animals led in a group by a boa constrictor named Auriel. With betrayal arriving on Mez's doorstep, she must figure out how to stop the Ant Queen, who wants to rule the rainforest. It takes you on a series of twists and turns, and I liked the suspenseful moments.
