A special one-shot set in the Ronin-verse! After the Last Ronin defeated Oroku Hiroto, Master of the Foot Clan, New York City was free for the first time in more than a decade. But along with the newfound freedom comes a dangerous power vacuum waiting to be filled, and without a common enemy in the Foot Clan, various factions are vying to take control. Longtime resistance leader April O'Neil finds herself and her loved ones-including four small mutant turtles she and her daughter, Casey Marie Jones, are raising and training together-once again caught up in the battle for the soul of the city. When April takes the young mutant turtles with her on a supply run into the city, they become lost and must find their way back to the sewer lair or risk becoming collateral damage in the newest power struggle overtaking the streets. Old memories mix with new realities as April and her four small charges race to get back home before it's too late. This 40-page special comes from the New York Times best-selling TMNT: The Last Ronin creative team of writers Kevin Eastman and Tom Waltz, illustrator Ben Bishop, and colorist Luis Antonio Delgado, and is an official tie-in to TMNT: The Last Ronin-Lost Years.
