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.
From Emily Calandrelli—host of Xploration Outer Space, correspondent on Bill Nye Saves the World, and graduate of MIT—comes the third novel in a fun illustrated chapter book series about an eight-year-old girl with a knack for science, math, and solving mysteries with technology.
Third grader and inventor extraordinaire Ada Lace likes nothing more than to tinker with mechanics like her robot, George. Her latest project is to fix up a ham radio, something that she could use to contact people on this planet…and beyond. The only problem is that she just can’t get it to work properly.
During a sleepover, Ada’s best friend Nina hears something strange coming from the radio in the middle of the night. A distant voice says, “Release the swarm!” convincing Nina that aliens are about to invade planet Earth.
Could Ada and Nina have stumbled upon something…extraterrestrial?
