Traveling to Terra Obscura with his son-in-law Val Var Gram for magic elixir that may save his daughter from dying during childbirth, Tom Strong finds an entire world under the threat of a dreaded plague that has taken 60% of the planet’s inhabitants.
Although he is able to reconnect with a pair of old friends, the Fighting Spirit and The Terror (or what’s left of him as brain is now encased in an android body), Strong doesn’t find the one man he’s traveled across dimensions to talk to. More troubling is the fact that just by landing on the planet both he and Gram may have become plague carriers who would doom their own Earth if they were ever to return.
Of course threats like this aren’t enough to get the science hero down and he remarks the pair will simply have to stamp out the plague and save an entire world before heading home with the formula needed to save the life of both Strong’s daughter and unborn grandchild. Another strong (pun intended) issue setting up a herculean heroic undertaking for Strong before he can make his way home. Worth a look.
