Captain America has battled soldiers, terrorists, and villains of all kinds. Now he’ll face a far more complicated enemy: his own body. When S.H.I.E.L.D. discovers that Cap is harboring an extinction-level pathogen hidden in his cells for decades, Cap’s greatest fear is realized: Until the virus can be cured, he’ll have to go into deep freeze. But he won’t be alone. Years ago, Cap’s greatest enemy managed the biggest coup of his career when he implanted his mind into a clone of Steve Rogers’ body–virus and all. And Red Skull isn’t the sacrificial type. Cap will have to put his archnemesis on ice–without exposing the virus. Can Cap stay alive long enough to capture Red Skull and return to his deepest nightmare? It’s a battle for perfect symmetry in this original prose novel!
