"Steve Rogers is dead! Long live Captain Zolandia! Captain America has spent twelve years as a fugitive wandering the desolate wasteland of Dimension Z, battling the Zola virus that threatens to strip him of his humanity and traveling with a boy he has raised as his own. The Sentinel of Liberty brings the fight back to Dimension Z's godlike oppressor Arnim Zola when Cap becomes the last remaining hope for the native species, the Phrox. A soldier with no nation waging a one-man crusade to stop the spread of Zola's consciousness in this world and his own, can Captain America turn the tide in the odd war of this backward realm? Battling savage mutates, Zola's own twisted take on a super-soldier, Captain Zolandia, and even his own adopted son, Steve Rogers stares death in the face and makes the hardest decision of his life when he pays the deadly price for escape from Dimension Z!" -- page 4 of paperback edition.
