The third field trip of the Time Warp Trio lands them in the heart of the Old West. Far from enjoying the pulsating adventure of TV westerns, however, Fred, Sam and Joe suffer the dust-choked, mosquito-infested monotony of a cattle drive - until the Indians show up. Once again the threesome utilizes a bit of 20th-century cunning to save their hides and outwit their opponents. Scieszka's zany sarcasm sets a lively pace and offers up subtle parodies of popular western stereotypes. (This time, the Indians get to be the good guys.) With clever wordplay, these collaborators' fans will no doubt gobble up this latest time-travel installment as they eagerly await the next one.
