"You're the greatest hero of the Marvel Universe, so why doesn't anyone remember you? Your name is Bob Reynolds. You prefer cartoons over CNN. You drink too much and are thirty pounds overweight. You're afraid of heights, hate crowds, and your wife blames you for your dog's moodiness. And you know you were once a super hero. You were the Sentry. But then something terrible happened. Something that threatened all life on Earth, something that caused your best friend--Mister Fantastic, the leader of the Fantastic Four--to betray you. Now it's happening again...and the Sentry must return. But at what cost?"--Back cover.
