I've read enough post-apocalyptic books recently to say this doesn't really fall into that realm. This is closer to the world of the Purge than anything else.
While I don't judge the writing as harshly as some have, I admit the structure sometimes just felt lazy and even uncomfortable with a good chunk of those issues involving the use of the dog Max. I swear sometimes I got the feeling the narrator wanted to make out with Max.
With those things said, it kept me interested and left enough open for a sequel/parallel series that I might look at if it happens. With the sale price I got this collection under, it was good enough for me to enjoy most of it as a gap read (reading between book collections/series that I do like a lot). I however would never pay anything close to full price for this.
