Harley Quinn, Deadshot, Captain Boomerang, Killer Croc--they're all villains, but as members of the Suicide Squad they're useful villains, taking on America's dirtiest and most dangerous covert missions for the good of the country--usually against their will. (Remotely triggered brain bombs do wonders for motivation!)
But now something has changed. A mysterious organization called the People has enlisted Task Force X leader Amanda Waller into a conspiracy to create dozens of new Suicide Squads around the world. Its goal: to eliminate the threat posed by all metahumans--heroes and villains alike.
When the original Squad's members discover the nature of the People's plan, will they seize this once-in-a-lifetime chance to take down the world's superheroes? Or will these incorrigible criminals prove to be the unlikeliest of saviors?
Writer Rob Williams (Trinity, Kingsmen: The Red Diamond) and acclaimed artists Gus Vazquez (The Flash), Agustin Padilla (Smallville) and Giuseppe Cafaro (Justice League vs. Suicide Squad) assemble the best of the worst in Suicide Squad Vol. 5: Kill Your Darlings, collecting issues #21-25 of the outrageous ongoing series.

Amanda Waller, director of Task Force X, has hand-picked the members of her Suicide Squad to handle any dirty job she throws their way. This time, however, what she wants belongs to one of Superman’s deadliest antagonists—and getting it is more important than ever.
With a sprawling international conspiracy threatening to destroy everything she has built, the Wall must go toe-to-toe with none other than Lex Luthor to secure the key to controlling the living weapon of mass destruction known as General Zod.
But no matter what power Waller may hold over him, Zod kneels to no one, and it’s not long before he and the rest of Task Force X are at each other’s throats. Will Waller’s plan to make this Kryptonian war criminal a full-fledged member of the Suicide Squad live up to its enormous potential? Or will it actually doom the entire planet to devastation and alien enslavement? The answer may surprise you!

Uniting acclaimed writer Rob Williams with superstar artists John Romita Jr. and Eddy Barrows, this volume also includes a bonus tale of international intrigue from legendary SUICIDE SQUAD writer John Ostrander and artist Gus Vazquez!
Deep within the world is a hidden flame—an inferno of hatred and vengeance that consumes everything it touches. In the aftermath of the war between the Suicide Squad and the Justice League, one of Amanda Waller’s greatest foes has seized that flame, and now he’s going to use it to burn down everything she holds dear—starting with her home base, the Belle Reve Penitentiary.
The result is one of the Squad’s greatest challenges yet: holding together as a unit while fighting to keep their fellow super-villains behind bars. When faced with the chance to escape Waller’s control, however, one member of the team will seize the opportunity—and launch a bloody betrayal in the process.
Can an enraged Harley Quinn track down the traitor—and take down the mastermind behind the mutiny—before Task Force X is terminally disbanded?
