In this dazzling memoir, the acclaimed writer behind Babylon 5, Sense8, Clint Eastwood’s Changeling and Marvel’s Thor reveals how the power of creativity and imagination enabled him to overcome the horrors of his youth and a dysfunctional family haunted by madness, murder and a terrible secret.

For four decades, J. Michael Straczynski has been one of the most successful writers in Hollywood, one of the few to forge multiple careers in movies, television and comics. Yet there’s one story he’s never told before: his own.

Joe's early life nearly defies belief. Raised by damaged adults—a con-man grandfather and a manipulative grandmother, a violent, drunken father and a mother who was repeatedly institutionalized—Joe grew up in abject poverty, living in slums and projects when not on the road, crisscrossing the country in his father’s desperate attempts to escape the consequences of his past.

To survive his abusive environment Joe found refuge in his beloved comics and his dreams, immersing himself in imaginary worlds populated by superheroes whose amazing powers allowed them to overcome any adversity. The deeper he read, the more he came to realize that he, too, had a superpower: the ability to tell stories and make everything come out the way he wanted it. But even as he found success, he could not escape a dark and shocking secret that hung over his family’s past, a violent truth that he uncovered over the course of decades involving mass murder.
