Marc Aronson is an author, editor, publisher, speaker, historian, and book producer. His mission is to inspire young people to ask questions, to look around, behind, and inside of the stories the world tells us. He writes a monthly column for School Library Journal on nonfiction for younger readers, and frequently speaks about boys and reading. Marc's books have been awarded the Robert F. Sibert Award for the best in children's nonfiction and selected as a New York Times Notable Book and a School Library Journal best book. In 2006, he was given the ALAN Award by NCTE for service to teenagers, and was named the local spokesman for the History Channel's Save Our History program. He lives with his wife and two sons in Maplewood, New Jersey. H. P. Newquist has authored more than a dozen books for both children and adults, including the critically acclaimed The Great Brain Book (Scholastic, 2005). To prepare for For Boys Only, Mr. Newquist went scuba diving with sharks in Australia, climbed the Great Pyramid in Egypt, drove some really fast cars, learned a few magic tricks, and read more books than he can count.
