"A lonely mouse lived in a small house beside a great palace. In the great palace lived a cat." Each night the mouse gazes up at the cat in the palace tower. Is the cat my friend? he wonders. Determined to find out, he bravely makes his way into the palace through a tiny hole and climbs all the way up to the tower, where the cat sits on the windowsill. "Hello, are you friend or foe?" he squeaks. This simple story by John Sobol has a surprising outcome, giving young readers a chance to draw their own conclusions. It is perfectly complemented by Dasha Tolstikova's subtle yet striking illustrations.
