Finding Callie

Miles and Callie have been best friends since they became neighbors in fourth grade. They knew everything about eachother by the time they got all the way to their sophmore year of high school, but as soon as junior year rolled around Miles found out that Callie was moved into a private school instead of public with him. They didn't see eachother that much anymore but they always met at the bus stop. When Callie didn't show up one day, Miles didn't think anything of it, but pretty soon weeks started going by and he just knew somthing wasn't right. He went to her house to find her gone with a single letter sitting on her bed with his name on it. The letter had specific instrutions on what to do to find her, but the journey turns out to be more dangerous than Miles thought it would be, and on top of all that he finds himself slowling falling for this missing girl. Can he figure out how to find Callie before time runs out?
