Zoe and Mark are children, watching their world falling around them. Their mom was cheating and eventually divorces their dad and has her sideguy come and live with them. Dejected, their father ends his own life. And, shockingly, the young lover that she choose over her husband has no interest in being a father figure and begins to take advantage of having a young woman (i.e. child) in the house.
Now we have a baby due from the 14 yr old Zoe. She won't say whose baby it is, like she's afraid to. And she is. And as bad as it is looks now, it's going to get worse.
I find Matt Shaw's work to be inconsistent. He's had some very good books, but also a number of rather pedestrian novels. Unfortunately this one comes more toward the latter. The framing of the story is strange - chapters follow individuals, often over multiple periods of time. So we go back and forth in time but are restricted to specific characters, eventually determining that the person we are following is dead/dying/abused/etc.
There is a twist of sorts, but it's called out earlier than in most books, so it's not a last-minute thing. Many readers will figure out the "twist" earlier than the book shares it, which is to no fault of Matt Shaw, as he's clearly drawing attention to the details for follow up reads.
At a brisk 88 pages, it moves along quickly but feels a little too tame to be "extreme" horror. There is a sad domestic story here, but with the clumsy story building structure it's impact is minimized, in my opinion. I wouldn't recommend this above most of Matt Shaw's work, but if you've already gone through most of them and enjoy his style, give it a look.
