The Adventures of Nick and Sam: Summer Adventures Box Set - Books #7, 8 and 9 (Nick & Sam)

The Perry twins are Nicolas (Nick) and Samantha (Sam) Perry. In the summer, they moved to Hope Springs with their parents, brother Andrew, and sister Lizzy. Hope Springs is a fictitious town in Colorado's mountains. This series follows the twins, their family, their friends, and the people they meet at school, church, and in town on their excursions.

This series offers Catholic culture in a straightforward and natural manner, and it encourages readers to consider the ramifications of their words and deeds. Some of the chapters are included in the Signs of Grace curriculum, and the Hope Springs "world" includes McCusker's adult's fiction Blue Christmas and Last Things. 

This series is written similarly to the Adventures in Odyssey series and the Magic Tree House series, and is recommended for readers ages seven and up, but can also be read by parents or teachers to younger children.
