A faded country house in the middle of nowhere. The guests are snowed in.

The murders begin.

Withering and waspish, Ursula Smart (not her real name) gate-crashes her mother's book club at an isolated country house for a long weekend retreat. Much to Mother's chagrin. Joining them are Mother's best friend, Mirabelle, Aunts Charlotte and Less, and Bridget with her dog Mr. Bojangles. It doesn't matter that they've read Gone Girl three times this year already, this retreat is their chance to escape bustling suburbia. But someone has other ideas.

A body is found in the grounds.

Is a lone killer hunting them? Or has one of their own group embarked on a killing spree?

What they need is to stop sniping at each other long enough to solve the mystery before the killer strikes again.

What they need is a guide to survive.
