Ant-Man - Second-Chance Man vol.1 TPB

Scott Lang has never exactly been the world's best superhero. Heck, most people don't even think he's been the best Ant-Man - and the last guy invented Ultron and joined the Masters of Evil, so that's saying something. But when the Superior Iron Man calls with a once-in-a-lifetime opportunity, Scott's going to get a chance to turn it all around and be the hero he's always dreamed of being. Sure he's been to prison. Sure he's been through a messy divorce. Sure he's been, um... dead. But this time is different! This time nothing is going to stop the astonishing Ant-Man!
