Multiple hurricanes wreak unprecedented devastation on Houston, Texas. The Serenity Six—genetically altered test subjects for a viral strain known as Serenity—escape the state prison in Huntsville to gorge their appetite for murder on society’s survivors. They soon become the acolytes of Id, a being of immense power and wanton appetites, who steps into our reality to prosecute mankind and destroy morality. And one family steps up to the fight—a family experiencing its own turmoil caused by a contentious divorce. The Stand meets 28 Days Later in this epic tale of genetic manipulation gone awry. There’s no such thing as an ordinary hero.

The dark, gritty dystopia of Escape from New York meets the isolated heroism of The Omega Man and the horrific reality of C.H.U.D. in this second Serenity novel. In The Serenity Strain: Stormbreak, three massive hurricanes ended the world. Six psychopaths escaped prison. And one mystical temptress named Id slipped into our reality. Now, the storms have passed. Houston's stunned survivors are waking up, wandering out of their broken homes, and looking for someone to show them the way. In Ironheart, heroes thrown together by circumstance face their greatest fears. Lauryn, Megan, Stavros, and Colt—a new champion from another reality—stand together as Id, Marsten, and their army of escaped prisoners move south to enslave the Bayou City. And now a new threat emerges as ravenous creatures born from man’s own vanity pour forth from another corner of the multiverse. Heroes aren’t born. They’re made.
