Amazing book! Super excited to read book 31 when it comes out! Dragon Masters is a very fun series!

[Efox · Rating 4 out of 5]

This series is absolutely one of our favorites. In August we re-read all 29 of them and for several this was probably our 10th+ re-read. The adventures of Drake, Rory, Bo, and Anna continue to engage my kids and be both comforting and familiar while being new and exciting.

The Chaos Dragon was great. What an interesting dragon and a fascinating concept to introduce in a thoughtful way. Thanks Tracey West for continuing this series. We still love it and can't wait to see what comes next. We hope the Chaos Vortex is more powerful than the Earthquake Dragon, but we love leaving the door open for more fun adventures.

We listened to the audiobook and completed it right after starting. My 7 year old was very into the story. We are wondering if this was the last book in the series. We hope not.

Another great adventure. This books are so easy to listen to and short enough for a trip during the traffic hour.

Very fun! The mini-Maldreds were a fun and creative villain. The dragon was a cool new twist on the dragons. A very enjoyable addition to the series!
