Nicolas (Nick) and Samantha (Sam) Perry are twins. They moved with their parents, their brother Andrew, and their sister Lizzy, to the Colorado town of Hope Springs. The likeable and engaging characters reflect the sensibilities and struggles of being Catholic in the quirky small town of Hope Springs, and in the many adventures that make the teachings of the Church come alive.

Nick and Sam are looking forward to an exciting summer. But problems arise when the move into the old family house causes conflicts with friends, the arrival of their six year-old cousin triggers chaos, and a strange event nudges the kids into an age-old mystery. Summer Blast brings family fun and inspiration together with the suprises of everyday life.
