Master puzzle maker Trip Payne has come up with another brain-busting collection that will wow youngsters. His Crosswords for Kids has sold nearly 60,000 copies, and his Great Crosswords for Kids is on its way to similar success; these oh-so-clever puzzles should scale the heights of popularity, too. Children will enjoy figuring out such kid-friendly clues as “Last name of the author of Curious George,†“One of Santa's helpers,†and “Sylvester the Cat chased him.†And while they're having a good time filling in the answers, youngsters will also improve their vocabulary, learn interesting facts, and boost their powers of concentration.
