"After stopping Dr. Z's nefarious plan and rescuing the unicorn horn, things haven't quite been the same for the Rescue Ops Acquisition Rangers. In order to pay the bills and support themselves, they open a zoo and gift shop. Scratch, Martie, Quito, and Ursa think it's a great chance to educate the public and teach people to be better to the environment. But Lug isn't so sure that this is the best use of their time and energy. After an incident when a kid sets a fire with a magnifying glass, Lug decides to leave the team and goes to do work that he thinks will actually make a difference: helping a group of smoke jumpers stop the wildfires in California. But it seems like the fires they're stopping may not be so natural-someone seems to be causing them to try and lure Lug to follow . . . It's going to take the help of all the Extincts to get to the bottom of it and save the day! With heart-racing action scenes, loads of humor, and an environmental message, this new book from New York Times bestselling author Scott Magoon is an exciting adventure from start to finish. The book will also include nonfiction back matter about extinct animals, climate change, and what kids can do to help!"-- Provided by publisher.
