Comet's Nine Lives by Jan Brett
Reading level: Ages 4-8
It all begins when Comet walks away from the lighthouse close to his birthplace on Nantucket Island. He visits a garden, a bookstore, a boat, and a party, and at each place he gets into trouble and loses one of his lives. Comet starts to worry. He longs for a home, a place where he'll be safe. Will he find one before he uses up all nine lives.
