In this hotly anticipated follow-up to the smash hit IQ, a New York Times Critics’ Best of the Year and nominee for the Best First Novel Edgar Award, Isaiah uncovers a secret behind the death of his brother, Marcus.

For ten years, something has gnawed at Isaiah Quintabe’s gut and kept him up nights, boiling with anger and thoughts of revenge. Ten years ago, when Isaiah was just a boy, his brother was killed by an unknown assailant. The search for a killer sent Isaiah plunging into despair and nearly destroyed his life. Even with a flourishing career, a new dog, and near-iconic status as a PI in his hometown, East Long Beach, he has to begin the hunt again—or lose his mind.

“Joe Ide is the best new discovery I’ve come across in a long time. And Isaiah Quintabe is the kind of sleuth not seen on the mystery landscape before. Righteous is a riveting follow up to IQ.” —Michael Connelly, author of The Late Show
