Book excerpt: Everything changes for Steve Rogers and Sam Wilson on the road to SECRET EMPIRE! Steve sacrifices all to defeat the Iron Nail and Arnim Zola, and is Captain America no more! Falcon takes over as a high-flying Sentinel of Liberty, until a Standoff in the town of Pleasant Hill draws in three men who have wielded the shield - Steve, Sam and Bucky Barnes! A world-changing power leaves Steve rejuvenated - so much so that he dons the red-white-and-blue once more! But with Sam still on the job, is the world ready for two Captain Americas? Then again, is the world the same as it was? Prepare for the secret history of Steve Rogers - and Hail Hydra!
