The after party / A.C. Arthur.

Enhanced descriptions from Syndetics:

Three women form an unbreakable bond in a sexy, suspenseful, and adventurous novel about empowerment and sisterhood through thick and thin.

Venus McGee, Draya Carter, and Jackie Benson are coworkers with a lot in common. They're smart, independent, driven, and deserving of recognition--certainly more than they've been handed by a demoralizing boss. He's the topic of conversation at their impromptu get-together after the company holiday party, where the threesome fantasizes about a life without him. There has to be an alternative to taking a deep breath and sucking it up. There is. It's just not the one they expected.

When morning comes, Venus, Draya, and Jackie are blindsided by murder--a twist of fate that brings a startling new challenge to the table and forces them to navigate a hair-raising detour they never saw coming. For better and (unless they can help it) for worse, it's going to turn their world upside down. What starts as a necessary bond of mutual trust soon morphs into an empowering and galvanizing friendship that Venus, Draya, and Jackie need now more than ever.
