This is one epic book. This arc has elements you don't find in your everyday comic book. The wife of Elongated Man is murdered and the greatest minds in the superhero community have no clue how the killer got in and out undetected by Human and Martian tech. A group of heroes search for the killer while exploring the metaphorical "line" and when and if it should be crossed.
The good: A large array of heroes both familiar and unfamiliar to the general public. An amazing stand alone mystery. The art is great and the writing might as well be art.
The Bad: The only bad thing about this book is parts are hard to read because you feel so terrible for some of these characters. Another plus for good writing though I guess.
I gave it 4.5 out of 5. There hasn't been a book like this book since this book..........yup that's right.
