The Paraskevases (Gracie Graves and the Kids from Room 402, 1995, etc.) take readers on another foray into bizzaroland. At midnight, a young boy stands on a station platform, far from the warm precincts of his bed. A train awaits him, but his fellow passengers are a very strange assortment--blockheads, devilish types, extraterrestrials, creatures right out of an intergalactic bistro. Above the din, ever so faintly, the boy hears the train's sinister warning: ""Never coming, never coming, never coming back."" In the dining car, he runs across another humanoid, Cecil (""I know my onions"") Bunions, a private eye. Bunions, hearing the train's mad refrain, fashions an elegant escape for the boy. The narrator bumps into Bunions a couple of weeks later and is never sure whether he's had a dream or a magical mystery tour. This piece of artful entertainment has plenty going for it--a touch of the forbidden (the boy is led to the station by a stranger), hair-raising illustrations that are ghoulish and surreal, a tone long on irony. The rhyming is imperfect, but it may not matter: This is not a book to read at bedtime.
