Let me get the Audiobook portion out of the way quickly -- Damron does a capable job. He didn't particularly wow me, but I had no complaints about his work. I could see myself really getting into a book he narrated.
This is essentially Gotham, season 9. Bruce is on the eve of graduation, turning 18 (yet his guardian, Alfred, is still treated as if he has any standing in his life), and finds himself on the wrong end of the law and serving probation by doing community service at Arkham Asylum. While there, he becomes fascinated by an accused murderer -- she's part of a criminal/political (technically a terrorist group, but the label was never used) group targeting Gotham's one percenters.
The line between the Bruce Wayne of this book and the Dark Knight we all know is pretty weak. You've got Alfred, Lucius Fox, Bruce's dead parents, Gotham City -- sure -- but there's nothing that distinctively Batman about them (as used here). Even when you throw in Harvey Dent as a troubled youth with a strong trust in the legal system as one of Bruce's best friend and numerous references to bats, and you're supposed to thing that you've got yourself the building blocks of the Caped Crusader. But it'd have been incredibly easy for this to be any other rich youth with a knack for electronics. This doesn't have to be a Batman story, it could be almost any generic YA hero.
If you want to read an inexperienced, fallible, Batman (as seems to be the case here), read Miller's Batman: Year One or Barr's Batman: Year Two -- they treat the character the way he should be treated. This book just wasn't. I got about halfway through (maybe a little over halfway) before I just couldn't take it anymore and decided to move on.
I liked the Wonder Woman installment in this series just fine -- why didn't this one work for me? Well, while Diana wasn't the hero we all know -- she was still clear in her purpose, driven to do right and capable. Bruce is none of those things -- which is odd, because he's typically been depicted as driven and single-minded since childhood. That's the Bruce we all know, and should've seen here.
I can see why some people will enjoy this, but I just can't bother to finish.
