Friends Like These: Kimberly McCreight

Ten years after graduation, a group of friends reunite in a remote estate in upstate New York.
It isn't a bachelor party, as they've led one of their friends to believe, but an intervention for an escalating drug addiction. They lost one member of their friendship group in college, and they'll do anything to make sure that doesn't happen again…
But from the moment they arrive, something doesn't feel right. And with so much shared history between old friends, it's inevitable that a secret or two will slip out over the weekend.
And one of them will lead to murder.
