This looked like another one of those Strangers movie type stories where a normal family gets attacked out of nowhere in the middle of nowhere and for no good reason. Those are usually pretty entertaining, sort of like survival tests, actually Strangers 2 Prey at Night was a really good example of that, a surprisingly entertaining and well done one, particularly for a sequel. But actually this book managed to spin the premise into something new. Same concept, a young married couple set off on a remote getaway to try to jumpstart their marriage, accompanied by the younger brother in law, the one who secured the palatial accommodations they are staying in, the place got all sorts of conveniences…and someone locked up in the basement. In fact the basement scene is so creepy, it’s easily the star of the show here. And then the owner of the place, obviously responsible for his basement guest, gets back and there is no way to know who’s telling the truth about things until it’s too late. It becomes something of a massacre and, of course, the battle for survival. Never heard of the author, she’s Australian (suppose that counts toward international reading, kinda sorta), the story might have been set anywhere, but maybe not in the US, going by how stunned the characters are to discover a gun on premises. Australia, like so many civilized countries, have very strict regulations about owning firearms. But yeah, there’s plenty of action, some suspense, nice pacing, enough thrills to comfortably qualify for a thriller, a variation on the invasion thriller genre. The writing is of above average quality for the genre, particularly for books with those ludicrous descriptions following the title (and oh how I loathe those), title alone should always suffice. For me most guests are unwelcome, it’s all an invasion of privacy one way or another, but fiction definitely takes it to extremes as fiction is wont to do. Quick read and plenty entertaining. For a random kindle freebie it’s well above most reasonable expectations.
