Spinning out of the hit series HARLEY QUINN, this six-issue miniseries tells the story-within-the-story of the unlikely super-duo's adventures in outer space! Hey, remember the panel gutter between panels 3 and 4 of page 20 of HARLEY QUINN #12? What? You don't? It's only, like, the most memorable panel gutter of the twenty-first century! We'll jog your memory-our heroes, Harley Quinn and Power Girl, were tossed through a teleportation ring, dropping them into galaxies unknown. It's a cosmic adventure beyond your wildest imaginings: Power Girl and Harley Quinn, stranded in a forgotten dimension, on the homeworld of the amorous warlord Vartox! They'll sacrifice anything they have to in order to get home-except their dignity. Kidding! That'll be the first thing to go. HARLEY QUINN writers Amanda Conner and Jimmy Palmiotti are joined by artist Stephane Roux (BIRDS OF PREY) and writer Justin Gray (ALL-STAR WESTERN) for an unforgettable tale of friendship, romance and butt-kicking! Collects HARLEY QUINN AND POWER GIRL #1-6.

Nightwing is busting a group of criminals when he discovers that his old friend and ally Speedy has come into town looking for him.

Then, in a second adventure teaming together the two Teen Titans, Nightwing and Speedy get caught up in a war between two rival gangs.

From the creative team of Amanda Conner, Jimmy Palmiotti and John Timms, this storyline explodes out of the blockbuster DC Universe Rebirth event. Comics' craziest couple face off in HARLEY QUINN: REBIRTH DELUXE EDITION BOOK 1, a hardcover collection of the first two best-selling paperback volumes. Since relocating from Gotham City to Brooklyn's Coney Island, Harley Quinn has transformed her apartment building into a haven for freaks, strays and other unstable vigilante antihero-types. With her freak-show friends, bestie Poison Ivy, other bestie Red Tool and the Gang of Harleys by her side, Harley's ready to face all of Brooklyn's deadliest threats—from zombie armies and giant robots to punk-rock gangs and department store Santas. But the one thing she's not ready for? The return of a certain Mistah J. He's promising to make amends, but not even Harley would be willing to give that whack job a second chance. Right? Collects #1-13.

Instead of battling the Dark Knight, she is now a researcher at the Gotham Botanical Gardens, studying the possibility of creating plant-human hybrids. But when her fellow scientists start turning up dead, she's both the natural leading suspect…and the only person (or plant) who can crack the case. To solve the mystery, Poison Ivy must team up-or throw down-with her oldest friends and closest frenemies, from Harley Quinn to Catwoman to the Swamp Thing. Can she keep things under control, or will she be responsible for a deadly new harvest? Find out in POISON IVY: CYCLE OF LIFE AND DEATH.

He's cut a swath through the Justice League and laid waste to Metropolis. He's Doomsday, and he has only one thing on his mind--killing the Man of Steel... permanently! The JLA desperately needs Superman's help, but he's busy on a mission of mercy: trying to save the life of the critically ill child of Lana Lang and Pete Ross. Can Superman turn his back on his two oldest friends in their time of need? Can the JLA stand against Doomsday on its own?

Rory Regan was the lucky one. He escaped the mission with his life. Now this battle-scarred war veteran has returned home, hoping to leave the guilt of his fatal raid on an ancient tomb behind him—along with the lives of all the friends and comrades he lost in the process. But from the sands of Israel to the streets of Gotham City, the horror has followed him home. Now the souls of the slain are wrapping Rory in supernatural armor, calling on him to avenge their deaths and defend his people from demonic invasion. He is no longer Rory Regan. He is…Ragman. And he'd better get used to it fast, because the war he fought in the Middle East is nothing compared to the apocalypse that awaits Gotham should he fail. He'll need to adapt to the incredible new powers of his awesome Suit of Souls—and figure out who he can trust, be they angel or demon—or nothing will be left but rags and ashes… From the acclaimed creative team of Ray Fawkes (Justice League Dark) and Inaki Miranda (Catwoman) comes a bold new reimagining of one of DC Comics' greatest cult heroes that bridges war, horror, fantasy, and the world of the superhero: Ragman! "The new Ragman series pulls pieces from Ragman's roots, while integrating a new origin and backstory that brings Ragman into modern-day Gotham City." — Comicosity

The clock is running out on the past…and if someone doesn't do something about it, there won't be any future. That's where the TIME MASTERS come in. Rip Hunter, inventor of the fabulous Time Sphere and leader of the legendary troupe of time travelers, is back with his crew to track through time a terrible conspiracy that has brought mankind to the brink of disaster. The only hitch is that no one but Rip and his friends believe that the conspiracy even exists. Time Masters travel back through the ages, tracing the threads of this conspiracy and coming into contact with some of DC's greatest heroes of the present and past, including Doc Magnus of the Metal Men, Booster Gold and members of Justice League International.
