When Curtis Brooks starts receiving phone calls from his older brother Wilt, who's been dead a week, he's sure it's to help him find evidence that will lead to a murderer's arrest. But Wilt claims he wasn't murdered; his calling, meant to help him adjust, is standard protocol for newly deceased at the Aftermart--a kind of inescapable, ever-expanding Walmart filled with discontinued products. Wilt's death ruled a homicide, Curtis embarks on a dangerous plan to find the killer, which soon has him scheming against a billionaire and floundering toward love with his brother's ex-girlfriend Suzy, all while struggling through high school and his single mom's poor choices. Why does Wilt help Curtis win over Suzy, even as he organizes a rebellion at the Aftermart? Who'd wanted him dead? Curtis risks his life to answer these questions, in the process forging a bond with his brother unlike any they've ever had.
