Philadelphia. Summer 1970.

Mike Callahan and Will Sullivan have been best friends since they were five. Two more summers and they're gone—out of this neighborhood, away from the violence and the secrets that haunt every street corner.

But things change in an instant.

Rob. Marlena. Sully. Mike. Four people whose lives will intersect on one scorching June day. Four perspectives on what really happened. And a neighborhood that will keep its secrets no matter the cost.

Friendships are forged in loyalty.

Lives are destroyed in silence.

A standalone prequel to the Book of Life series. No redemption. No easy answers. Only truth.

For fans of Dennis Lehane's Mystic River and S.E. Hinton's The Outsiders.

119 pages, Kindle Edition
