There's A Troll Under Memaw's Porch in Bloomington, MN

Set in a summer many years ago, a five-year-old girl named Nikki discovers a small two inch troll living under her grandparents' back porch. Mrs. Troll won't come out because she's afraid of a big giant named Willie. She tells Nikki her sad story how she became lost and doesn't know how to get back to the forest.
Can Nikki help Mrs. Troll find her way home without running into the giant?
