This is such a fun book!!! I loved The Mutant Mushroom Takeover and it was great to see Maggie and Nate's next adventure. Once again there were a ton of engaging STEM elements and plenty of action. It was a fast-paced, quick read with so many quirky animals, but my favorite part was the warm friendship that Maggie and Nate share and the family bonds that we got to see between Maggie and her older brother who was dealing with the aftermath of his troubles in book one, and seeing Maggie get to spend some time with her dad, too. The voice in this novel is spot on for middle grade, and while I enjoyed the adventure as an adult, I can't wait for my eleven-year-old to read it because it feels perfectly accessible and engaging for readers her age. Thanks NetGalley and Simon & Schuster for the free eARC to review.
