Andrew Lost is a series of children's science fiction adventure novels written by J. C. Greenburg and published by Random House from 2002 to 2008. It features a boy inventor named Andrew Dubble whose inventions rarely work the way he expects them to. There are 18 books in the series and they constitute five complete stories, each released consecutively. The chapter books were illustrated by Debbie Palen (volumes 1–4), Mike Reed (5–6), and Jan Gerardi (7–18). Characters Andrew Dubble — Andrew is the main character of the series. He is ten years old; he apparently comes from a wealthy family, because they can afford their own helicopter and Andrew travels to various places in the world periodically. Andrew loves to invent things. He invented The Atom Sucker in books 1–4 and the Goa Constrictor in books 13–16. Usually his inventions go awry, resulting in a series of books where Andrew is constantly trying to set things right again. Judy Dubble — Judy is Andrew's 13-year-old cousin. Although she does not like Andrew very much, she is usually stuck with him and is with him for most of the story. THUDD — Thudd is a robot that was given to Andrew by his Uncle Al for his seventh birthday. His name stands for The Handy Ultra-Digital Detective. THUDD is small enough to fit inside Andrew's pocket. THUDD talks in a squeaky voice and his sentences are always preceded by a "meep" noise. THUDD knows everything and constantly points out scientific facts to Andrew and Judy. Judy is not always tolerant of THUDD's superior knowledge, and once threatened to take out his batteries if he wouldn't stop talking. THUDD's most important rule is that he must never get wet. Uncle Al — Andrew's uncle is a scientist who probably has invented more than Andrew has. He sometimes treats his nephew Andrew to various gadgets (including Thudd). Uncle Al usually has a role in the plot of the story, but is not usually present while Andrew, Judy, and THUDD are off having an adventure. Plots Books 1–4 Illustrated by Debbie Palen (2002–2003). The first book, Andrew Lost on the Dog begins just after Andrew has finished building the Atom Sucker. He is testing it when he accidentally shrinks himself, Judy, Thudd, and a helicopter to the size of a dust mite. He and Judy are inhaled by a neighborhood dog named Harley and
