    An epic prequel to the smash-hit graphic novel TMNT: The Last Ronin, where readers discovered who the Last Ronin was, Lost Years shows the thrilling journey of how he came to be.

    In the smash-hit miniseries The Last Ronin, readers witnessed the final gut-wrenching days of the Heroes in a Half-Shell. For Michelangelo in particular, the march to his heartbreaking last battle was long and dangerous, taking him from New York City to Japan, across Asia and Europe, and then back home again to administer final justice against those guilty of killing his family. 

    But what happened during those fateful years when he had only the need for vengeance and Master Splinter’s journal to guide him? What battles did he fight? What hard lessons did he learn? The time has come to find out as original miniseries writers Kevin Eastman and Tom Waltz join artist Ben Bishop to reveal what adventures the Last Ronin experienced during his vengeful journey. And in the present, a new master, Casey Marie Jones, prepares her young terrapin students to be the next generation of Teenage Mutant Ninja Turtles!

    Collects the five-issue series and the TMNT: Lost Day Special.

    If you need more of The Last Ronin, read the sequel, The Last Ronin II—Re-Evolution!
    Kevin Eastman began drawing as soon as he was able to hold a crayon. His discovery of comic books gave meaning to his crazed doodling. When he discovered and studied the work of Jack Kirby, Russ Heath, Richard Corben, Vaughn Bode, and John Severin, he began to hone his craft. His first published work appeared in 1980, a year or so before he met Peter Laird. In May 1984, Eastman and Laird published Teenage Mutant Ninja Turtles #1, creating the hit Heroes in a Half-Shell.

    Tom Waltz is a former active-duty U.S. Marine, Desert Storm vet, and former California National Guard military policeman. He is an editor for IDW Publishing and the writer of critically acclaimed comics and graphic novels, including Teenage Mutant Ninja Turtles; The Last Fall; Finding Peace (with Nathan St John); the Silent Hill books Sinner’s Reward, Past Life, and Anne’s Story; and others. He has also written for video games, including Silent Hill: Downpour, Ghostbusters: Sanctum of Slime, and the TMNT games Brothers Unite and Mutants in Manhattan. He grew up in Clinton, Michigan, and lives in San Diego with his wife and two children.
