dementomstie 's review for:

Nine Lives by Peter Swanson
4.0

This is very much a modern "And Then There Were None". It starts without giving away the pastiche, but by the end it's full blown homage.
That's not too say that this takes place over a weekend, or that the characters are all isolated, but it ultimately has the same structure.
Very good book, good use of modern style for a classic story.
