Barney's boring seaside vacation suddenly becomes more interesting when the cottage next door is occupied by three exotic neighbors who are addicted to a game they call "Interstellar Pig."

The daring game of intergalactic chase that thrilled a generation of science fiction readers in Interstellar Pig has started again, and round two is deadly! This sequel to William Sleator's sly masterpiece takes readers on another hunt for the sinister Piggy, this time in the far reaches of space. Poor Barney has a boring after-school job, earning money to repay his parents after their beach house is destroyed in a battle with aliens. Of course, they don't believe that aliens did the damage. No one, in fact, realizes that sixteen-year-old Barney saved the world by outsmarting the visitors at their violent game, Interstellar Pig. No one but the aliens, and for them the game is far from over. Barney is about to be drawn into the contest again, becoming the unwilling partner of a chatty intestinal parasite; the potential snack of giant, man-eating crabs; and the competitor of a stinger-happy seven-foot wasp woman. Life just got a lot more interesting.
