Like her classmates Iggy and Rosie (stars of their own New York Times bestselling picture books Iggy Peck, Architect and Rosie Revere, Engineer), Ada has always been endlessly curious. Even when her fact-finding missions and elaborate scientific experiments don’t go as planned, Ada learns the value of thinking through problems and continuing to stay curious. Ada is an inquisitive second grader who was born to be a scientist. She possesses an unusual desire to question everything she encounters: a tick-tocking clock, a pointy-stemmed rose, the hairs in her dad’s nose, and so much more. Ada’s parents and her teacher, Miss Greer, have their hands full as the Ada’s science experiments wreak day-to-day havoc. On the first day of spring, Ada notices an unpleasant odor. She sets out to discover what might have caused it. Ada uses the scientific method in developing hypotheses in her smelly pursuit. The little girl demonstrates trial and error, while appreciating her family’s full support. In one experiment, she douses fragrances on her cat and attempts to place the frightened feline in the washing machine. For any parent who wants STEM (Science, Technology, Engineering, and Math) to be fun, this book is a source of inspiration that will get children excited about science, school, learning, and the value of asking “Why?” Check out all the books in the Questioneers Series: The Questioneers Picture Book Series: Iggy Peck, Architect | Rosie Revere, Engineer | Ada Twist, Scientist | Sofia Valdez, Future Prez | Aaron Slater, Illustrator | Lila Greer, Teacher of the Year The Questioneers Chapter Book Series: Rosie Revere and the Raucous Riveters | Ada Twist and the Perilous Pants | Iggy Peck and the Mysterious Mansion | Sofia Valdez and the Vanishing Vote | Ada Twist and the Disappearing Dogs | Aaron Slater and the Sneaky Snake Questioneers: The Why Files Series: Exploring Flight! | All About Plants! | The Science of Baking | Bug Bonanza! | Rockin’ Robots!

From Emily Calandrelli—host of Xploration Outer Space, correspondent on Bill Nye Saves the World, and graduate of MIT—comes the first novel in a brand-new chapter book series about an eight-year-old girl with a knack for science, math, and solving mysteries with technology. Ada Lace—third-grade scientist and inventor extraordinaire—has discovered something awful: her neighbor’s beloved Yorkie has been dognapped! With the assistance of a quirky neighbor named Nina (who is convinced an alien took the doggie) and her ever-growing collection of gadgets, Ada sets out to find the wrongdoer. As their investigation becomes more and more mysterious, Ada and Nina grow closer, proving that opposites do, in fact, attract.

Published two weeks after his seventieth birthday, Ada, or Ardor is one of Nabokov's greatest masterpieces, the glorious culmination of his career as a novelist. It tells a love story troubled by incest. But more: it is also at once a fairy tale, epic, philosophical treatise on the nature of time, parody of the history of the novel, and erotic catalogue. Ada, or Ardor is no less than the superb work of an imagination at white heat. This is the first American edition to include the extensive and ingeniously sardonic appendix by the author, written under the anagrammatic pseudonym Vivian Darkbloom.

A town built on a landfill. A community in need of hope. A girl with a dream. A man with a vision. An ingenious idea.
