What's the world like without the TMNT? Since their time-spanning victory over Armaggon, the Turtles have started to pursue other interests, leaving a void in New York among humans and mutants alike. This special issue explores the effects this change has on those connected to the brothers, from Old Hob to Jennika, across the five boroughs and all the way through Mutant Island. It's hard to tell how important someone is until they are gone. And who better to write such a story than Tom Waltz, the man who scripted the first 100 issues of IDW's series and the co-writer of The Last Ronin, and resign TMNT artist Gavin Smith!

Also, get your first glimpse of what is coming in a special prequel to the new TMNT #1, written by superstar scribe Jason Aaron (Scalped, Batman: Off-World) and drawn by white-hot artist Chris Burnham (Batman, Inc., Die!Die!Die!). Donatello has had a hard time since he came back from the future, and he's found himself in an unexpected place.
