This collection is a side companion of the Infinite Crisis story. In this one, Lex Luthor is organizing all the villains into one group to devise an attack against the Justice League. A small collection of villains do not want to join and they form their own group. In true comic book fashion, these two groups clash. 
 I read the main story of Infinite Crisis and I am attempting to read its side pieces. This one was a pleasant surprise as I did not think this was up my alley. I am not the biggest DC fan but I knew a little information about the characters that form the Secret Six. The only one I didn't was Catman who ended up being the main character. To my surprise he really stood out and I took a liking to him. The collection had the deceptions and battles one hopes to see in a collection. I enjoyed the one on one battle between Deadshot and Deathstroke. As of the artwork I thought it was excellent even though the reader can tell it is a little dated. 
 I have read several stories associated with the main story and this is one of the better ones. The serious DC fan will really like this one as this collection has a bevy of villains. One doesn't have to prior knowledge of this universe to enjoy it though.
