Simpsons Comics Showstopper TPB

"The curtain rises on a 'classic' tale of survival as the Simpson family is stranded on a deserted island. Then, with the Nuclear Power Plant set to self-destruct, only one man can save everyone in Springfield and he's got just 25 hours to set things right. It's about to be the longest day of Homer Simpson's life! And when Mr. Burns goes to a spa to be rejuvenated, he comes back a new man-literally! Who is this pretender, and why is he selling off all of Mr. Burns belongings? And where is the 'real' Mr. Burns? Is he alive and well, or did he 'exit stage left'?"
