Tess, Terrorists and the Tiara

Thirteen-year old Tess has never been able to compete with her “perfect” older sister, but
now she must—if she wants to inherit her grandmother’s priceless tiara.
The two girls have been invited to their grandparent’s lake house for the
summer to help take care of Grandma who’s been diagnosed with Alzheimer’s
disease. The sister who earns the most “helpful points” wins the former
beauty queen’s crown.

It’s not easy for Tess, who seems to always get things wrong despite best
intentions. But when a secretive family moves in nearby and Grandma
disappears, Tess learns a lesson about prejudice, fear, and the real value
of doing good—a lesson that may be worth even more than the tiara.
