Red Hood: The Lost Days ties 3 of my favorite Batman storylines together...A Death in the Family, Hush, and Under the Red Hood. 
 Jason Todd, Batman's 2nd Robin, was killed killed by the Joker. Somehow, he was brought back from the dead and dug his way out of his grave. Talia al Ghul takes him under her wing. She sets him up with various training opportunities to enhance his skills and take them to a level Batman never did...to kill. 
 Jason is set on revenge. He not only wants to kill The Joker, but wants to make Batman suffer. He feels that Batman could have done more to avenge his killing. In the end, he is not able to kill the Joker or Batman and decides to become the protector that Gotham needs. He is willing to take things to the next level and give the city what it truly needs. 
 Overall, I really enjoyed the story. Telling the story of how Jason Todd came back to life and fill in the blanks between A Death in the Family and Under the Red Hood. No one knows the post-Robin Jason Todd better than Judd Winick. The art throughout enhanced a great story. 
 My only complaint is that I wished they would have gone into more detail about Jason's resurrection. They explain him coming out of his "walking coma", but they never really explained how he was able to come back to life.
