"Whether running Stark Industries or suited up as Iron Man, Tony Stark has dedicated his life to making sure his technologies do not harm others. When S.H.I.E.L.D. agent Coulson informs Tony that two Avengers went missing while looking into one of his inventions, Tony immediately transforms into Iron Man and jets off to find them! But his simple rescue turns out to be ... Not so simple. Along the way he must face mutating dogs, robotic sharks, and freaky shape-shifting monsters from another dimension! As Tony tries to take on the problems himself, he realizes he needs help from his fellow Avengers. But will they arrive in time? Or will Tony be left out in the cold against another threat, The Space Phantons?"--Back cover
