Peter Heller, The Dog Stars
As with The Road, we have a (mainly) homosocial text in The Dog Stars.
Further, as with The Road, we have a text in which, for a large portion of the narrative, the response to the event is that everyone who is not within the group (and once more our group is a dyad of two males) is a dangerous enemy who must be killed. And notice that, mainly, we are meant to see this as the correct response. That is, the text (mostly) does not criticize Bruce Bangley or his violent ways.
