Kill Your Husbands [Audiobook]

It was supposed to be fun. A relaxing trip to a remote mountain retreat where there's no phone reception. Three couples, friends since high school, are looking forward to a weekend of drinking, reminiscing and flirting.
When someone suggests swapping partners, it doesn't seem like such a bad idea. The lights will be switched off, for privacy. It's not really cheating if you don't know who you were with, right? But when the lights come back on, one of the men is dead. No-one can agree who was in which bedroom with whom. Their phones don't work, and the car keys are missing. They can't get back down the mountain. And this killer is just getting started.
Now Senior Constable Kiara Lui has to work out which of them is lying, and why.
