A boy . . . a mysterious letter . . . twelve clues . . . a girl . . . a dad . . . two very strange strangers. These are just the basic ingredients in this adventure served up by Dashner in what is the start of a series that will capture the imagination of young and old alike. Atticus Higginbottom (Tick to all who know him) is smart, well-adjusted and something of a loner at school, preferring his family, the library and the Internet to his classmates. So he’s surprised to receive a letter postmarked in Macadamia, Alaska, from someone he’s never even heard of. But he’s intrigued and makes a commitment to join with his correspondent to “save many lives.” Though there are chunks of text that are overwritten, the telling is generally laced with a strong sense of humor and a sure hand at plot; the author is plainly in tune with today’s fan base. Let the adventure begin! (Science fiction. 10-12)
