Depraved Indifference by Joseph Teller

A sports car, speeding in the wrong lane, forces a van off the road. Bursting into flames, all nine occupants of the van are killed – eight of them children.

Criminal defence attorney Harrison J. Walker, known simply as Jaywalker, is trying to keep his nose clean while serving a three–year suspension. But when a woman seduces him into representing the driver, a man who also happens to be her husband, things get messy.

Jaywalker tries to stay focused on his goal – limiting the damage to his client by exposing the system's hypocrisy regarding drunk driving. But when he rounds a blind corner in the case, he collides with a truth that could change everything.
