You might want to read Cej's review here although I have a slightly different take, mainly because I enjoyed it more. The son of Nazi Baron Zemo wants to mess with former and current Captain America by forcing the the new Captain/Winter Soldier/Buckey to face the wrongs he's done and his clear inferiority to his mentor. Of course Zemo could simply kill him, but where's the fun in that? In The Trail of Captain America, our hero has to deal with the legal fallout of Zemo and the Red Skull's daughter (Sin) as they continue to mess with the Captain. They are interesting stories with good focus of heroes and villains, but I feel that it is leading up to something that hasn't happened yet, but should happen soon.
