Colin and Duck have finally settled into their castle. Vampires and ducks don't always get along, but Colin and Duck have discovered they have lots in common--they love gardening, trampolining and watching movies together. Colin is so excited when his grandma comes to stay, but before long Colin realizes that Grandma likes things done a certain way: she sleeps in the day, prefers cobwebs to cleaning, and even has a pet CROCODILE! Worst of all, Grandma says that Duck has got to go. What's a vampire to do? Colin's Grandma is a hilarious story about family, growing up, and standing up for yourself.
