Harley Quinn's back in Coney Island for a long-overdue reunion with old friends, old haunts, and…an old time machine? Yep, you read that right. A mysterious benefactor has left Harley a time machine. What could go wrong-right? Funny you should ask. Turns out the entire DC Universe-including Wonder Woman, the Flash, Aquaman, Batman, and li'l baby Supes-is thrown into chaos, and not the fun kind. But with every step Harley takes to right various wrongs, she creates another reality in the Multiverse…ones where things still suck. Worse, Starro has assembled a Suicide Squad of his own to conquer this new set of realities. With a time machine and a tough, scary, alternate-universe Harley at her side, maybe-just maybe-she can make things right again. And who the heck gave Harley Quinn a time machine in the first place? The answer needs to be seen to be believed! Harley's timehopping, universe-screw-upping adventure cannot be missed! Collects Multiversity: Harley Screws Up the DCU #1-6.

Harley is set to begin her new life, but she needs a job first. Enter the Coney Island Roller Derby! It's game time as Harley sets out to destroy her competition—literally.

The creative team that transformed Harley Quinn forever returns to shake up her world once more-and this time, the gloves are off! Harley Quinn has avoided Gotham City ever since she broke up with The Joker and found a home in Coney Island. But when she gets an offer she can't refuse, she has no choice but to slip back into the city as quietly as she can, hoping to be gone before anyone-especially her ex-learns she's been there. But for Harley, "as quietly as she can" is plenty loud...and before she can say "Holee bounty hunters, Batman," The Joker's sicced every super-villain in the city on her pretty ombré head-and the only team tough enough (or crazy enough) to come to her defense is the Birds of Prey…if they can put up with her. Collects Harley Quinn & the Birds of Prey #1-4.

With just five dollars and a knapsack to her name, 15-year-old Harleen Quinzel is sent to live in Gotham City. She's not worried, though-she's battled a lot of hard situations as a kid, and knows her determination and outspokenness will carry her through life in the most dangerous city in the world. And when Gotham's finest drag queen, Mama, takes her in, it seems like Harley has finally found a place to grow into her most "true true" with new best friend Ivy at Gotham High. But when Mama's drag cabaret becomes the next victim in the wave of gentrification that's taking over the neighborhood, Harley's fortune takes another turn. Now Harleen is mad. In turning her anger into action, she is faced with two choices: join activist Ivy, who's campaigning to make the neighborhood a better place to live, or team up with her anarchist friend Joker, who plans to take down Gotham one corporation at a time. From Eisner Award and Caldecott Honor-winning author Mariko Tamaki (This One Summer) and Eisner Award-nominated artist Steve Pugh comes a coming-of-age story about choices, consequences, and how a weird kid from Gotham goes about defining her world for herself.
