Finley is upset when he learns about slavery at school. Why would anyone treat another person that way? The Sweets Shop always gets special customers, but when Harriet Tubman stops in and tells them about the Underground Railroad, her timing couldn’t have been better. But Finley and Fiona don’t just want to hear about it. They want to help! Will Fiona and Finley be able to help Harriet and the runaways escape to freedom? Fiona and Finely are brother and sister who spend their time helping in their parent sweet shop, baking, going to school, oh yeah, and traveling through time! Flying over the Atlantic, helping with the Underground Railroad, and seeing the discovery of electricity are just a few of the many adventures Fiona and Finely go on. Time Hop Sweets Shop introduces influential historical figures with engaging adventures. Each book in the series has a short biography, comprehension questions, and a Q & A with the author.
