Hap Collins is a straight, white, liberal, blue-collar tough guy. Leonard Pine is a gay, black, Republican combat veteran. Best friends who've shared a succession of low-wage odd jobs that have gotten them into even odder situations dealing with lowlifes, now the duo delivers their own brand of ass-kicking justice as private investigators.

In this brand-new story, a day's fishing lands Hap and Leonard their biggest catch ever: the Rolling Literature bookmobile. A pillar of rural African American communities in East Texas, the renovated school bus vanished fifteen years ago – along with its driver, Harriet Hoodalay, aka Hoodoo Harry – reappearing just in time to crash Leonard's pickup into a creek. Behind the wheel was a twelve-year-old boy who didn't survive the accident.

The kid was clearly running scared, but who was he running from and how did he end up in the driver's seat of the missing bookmobile? The first solid lead in a case that started more than a decade earlier with Hoodoo Harry, this mystery of a small town's dark and disturbing past will take all of Hap and Leonard's wits – and fists – to solve.
