What if your friend - someone admired, envied, and fervently sought after by everyone who knew her - was really a dangerous sociopath? In her latest novel, "Cocktail Hour," mainstream fiction author Tara McTiernan answers that question as she takes you on a wild roller coaster ride of thrilling highs and terrifying lows in this gripping novel about friendship gone horribly wrong. Spring in glamorous uber-rich Fairfield County, Connecticut is a time of beginnings: a new diet for the approaching summer spent out on the yacht, fresh-faced interns being offered up at the office as the seasonal sacrifice to the gods of money, and corporate takeovers galore. Five women in their thirties have a brand-new friendship, too, one that fed and watered regularly at local hotspots over cocktails. With all of their personal struggles - Lucie's new catering business is foundering due to vicious gossip, Kate's marriage is troubled due to an inability to conceive, Chelsea's series of misses in the romance department have led to frantic desperation, and Sharon's career problems are spinning out of control - the women look forward to a break and a drink and a chance to let their guards down with their friends. And letting their guards down is the last thing they should do in the kind of company they unknowingly keep with the fifth member of their cocktail-clique: Bianca Rossi, a woman who will stop at nothing to have it all. As each woman's life is affected by this she-wolf in sheep's clothing, the truth starts to come out, but will they see it before it's too late? Or will their doubts about their own perceptions and gut feelings stop them from protecting themselves in time? Exciting, chilling, and emotionally charged, Tara McTiernan delivers a delicious page-turner that will change your view of everyone you think you know.
