Marley the loveable, trouble-making yellow lab stars in another holiday adventure in the picture book Trick or Treat, Marley! by John Grogan, author of Marley & Me. Marley's family is throwing a Halloween party. Cassie and Baby Louie are having lots of fun putting up spooky decorations. And Marley's having even more fun destroying them. The kids hang a creepy skeleton. Marley runs away with the leg bone. The kids string fake spider webs on the stairs. Marley sweeps them up with his tail. The kids carve pumpkins. Marley gets his head stuck in a jack-o'-lantern. Worst of all--he eats every piece of Halloween candy! Will Marley's family be able to have any Halloween fun with their naughty puppy around? Richard Cowdrey's illustrations bring the charming and mischievous Marley to life.
