When Aunt Adelaide sends thirteen-year-old cousins Ivan and Daphne on a treasure hunt in the rain, they never expect to stumble into a whole new world--an enchanting land where words and numbers run wild. They are surprised again when the first people they meet beg them to find Lexicon's missing children, who have wandered off, bewitched by lights in the sky. 
Trekking between villages in search of clues, the cousins encounter a plague of punctuation, a curious creature, a fog of forgetting, the Mistress of Metaphor, a panel of poets, and the illogical mathematicians of Irrationality. But when a careless Mathemystical reflects them across the border into the ominous Land of Night, their peril deepens. 
Kidnapped, imprisoned, and mesmerized--with time running out--will Daphne and Ivan find a way to solve the mystery of lights in the sky and restore the lost children of Lexicon to their homes?

With time travel and mysteries that need solving, the Galactic Academy of Science (G.A.S.) series instructs readers on how to think like scientists. Under the guidance of a Dude or Dudette from the future, the middle school characters are faced with treacherous, present-day crimes that require a historical knowledge of science in order to be solved. From investigating problems to analyzing data and constructing explanations and solutions, this series blends elements of sci-fi with educational methods that distill the key thinking habits of scientists and engineers.
When the Russian scientist Professor Gufov accuses Clinton of stealing his invention, all Mae and Clinton want to do is get away and work on their science project. But that’s before a Dudette from the future tells them about the Galactic Academy of Science and sends them on a mission back in time to beef up their scientific knowledge. Mae and Clinton meet Dmitri Mendeleev, Niels Bohr, John Bardeen, William Shockley, and Robert Noyce. They break up a séance, escape the Gestapo, jump from a plane, and return with enough understanding of how electronics work that they can tackle the mystery of the Russian scientist and search for the missing diamond chip.
