Batman: Nightwalker by Marie Lu is the second of the DC Icons novels.
Finished on: 2.5.2019
[Here’s my review of the first novel in the loose series.]

Plot:
The Nightwalkers are hunting the rich people of Gotham City. Bruce Wayne is about to be one of them – as soon as he turns 18, he will inherit his family’s fortune. But first, he has to do some community service in Arkham Asylum prison. As he scrubs the floors there, he meets Madeleine, one of the Nightwalkers who will talk to nobody but Bruce. But what really is the reason for Madeleine’s apparent confidence in Bruce? Bruce will have to figure out what to do with her and her interest in him – and that’s not all he has to figure out.

Batman: Nightwalker didn’t really work for me. It wasn’t completely bad, but it didn’t dig into Batman as a character as I would have liked. It’s okay to read, but it doesn’t really have staying power.
