The FF thought the worst they would have to deal with on their arrival back on Earth was the media buzz over their trip to the moon. They were wrong! The Puppet Master is back & he’s taken control of Sub-Mariner to use against The FF! Will the team discover who’s really behind the attack on them in time? If they don’t, they may be forced to put a stop to Sub-Mariner for good…or die trying! Also, Sue is again forced to confront her feelings for Reed & her strange attraction to Namor.
