The absolute value of Mike

Mike, a fourteen-year-old boy with a math learning disability, is sent to rural Pennsylvania for the summer to work on an engineering project, and while his plans to impress his mathematician father fall flat when Mike discovers the project has nothing to do with engineering, he learns much more valuable lessons while working with his eccentric, elderly aunt, a homeless man, and a punk rock girl as part of a town-wide effort to adopt a Romanian orphan.
