Because of a tragic event that took place when he was five-years-old, seventh grader Kameron Boyd can't make himself speak to adults when he steps outside his home. Kam's mom hopes his new school will cure his talking issues, but just as he starts to feel comfortable, financial problems threaten the school's existence.

Then a letter arrives with the opportunity to change everything. Kam learns that he and several others have been selected as potential heirs to a fortune. He just has to solve a series of seven riddles to find the treasure before the other students. If he succeeds, he'll become heir to a fortune that could save his school.

The riddles send Kam on a scavenger hunt through the churches of Chicago. But solving them won't be easy. With the school's bully as one of the other potential heirs, Kam and his friends must decipher the hidden meanings in artwork and avoid the mysterious men following them in a quest to not only keep the school open, but keep Kam's hopes for recovering his voice alive.
