Grandson and grandpa run away together for a one-night adventure in this chapter book from Swedish great Ulf Stark.        I hate the food here, Grandpa said. They’ve taken all the joy out of it. Not even the water tastes any good.Perhaps you should run away, I suggested.   I did a lot of that when I was young, he said. But I think it’s a bit  late now…     But by the time I had to leave for the bus, we’d made a plan.
