I respect what Barnes is trying to do here, but Nobody just didn’t work for me. I like that the premise is unique, but its intrinsic limitations made it impossible for me to finish the book.
The problem with two protagonists who are “practically invisible in every way” is that no one notices or cares about them. Claire’s own parents forget she exists, and other people fail to register her presence even when she bumps into them hard enough to knock what they’re carrying out of their hands. The lack of meaningful interactions results in a boring plot.
The rare cases when Claire and Nix do manage to get someone to acknowledge their presence are unsatisfying. At one point, Nix confronts his boss and demands to know why he has been ordered to kill a seemingly innocent girl. Nix is angry, threatening, and obviously dangerous – he’s an assassin, after all – but his boss is completely unfazed. She’s not afraid of him, or angry, and even when Nix wraps his hands around his boss’ neck and tries to choke the answer out of her, she barely fights back.
A book like this just isn’t sustainable. The romance between Nix and Claire can’t compensate for the anticlimactic nature of the rest of the relationships in the book. It’s possible that the novel picks up pace as it goes on, but I didn’t stick around to find out.
