I'm really enjoying the owls storyline, and I particularly like the way they filled in the backstory of the Talons in these. It gave them more of a human angle and explored their motivations and how they were enticed into the path they followed. 
 Is there another volume of this? They mention Red Robin and show him in the 'credits' but there wasn't any sign of him during the action. 
 My one gripe is that if I'd bought these vols first off, rather than reading through the library in the order I did, and THEN discovered that several of the stories from Night of Owls are repeated in this collection I would not have been happy considering the price of graphic novels.
