In her book, Grandma's Cow, author Donna Spevack introduces us to Sam. Spending summer vacation with his grandparents delights him more than anything else. He loves the farm and the animals, and especially the delicious treats Grandma makes for him. But there's something different about this visit. Sam notices the milk Grandma serves him is colored green and tastes like pistachios. The next day, the milk is blue and tastes like blueberries. As Sam helps Grandpa milk the cows, he notices each cow's milk has a different color and flavor. There is chocolate, peppermint, banana, and other flavors. Although it may seem like fun, nobody wants to buy the farm's milk anymore, and his grandparents may lose the farm. Sam decides to unlock the mystery behind the cow's milk and save his grandparents' farm. Grandma's Cow is a fun story about an ordinary boy in extraordinary circumstances. Readers of all ages will enjoy the story and the author's beautiful illustrations.
