One late wine- and gossip-fueled night, four friends on a lark create a fateful test of friendship -- one that challenges the very principles and boundaries of their alliance. To pass it means to never, at any cost, betray one another. Twenty years later, they must face that ultimate test. We meet them at the dawn of their camaraderie in the 1980s and already each woman is distinguished from the other: Tamsin, the compassionate mother hen; Reagan, the brazen and clever overachiever; Sarah, the seemingly perfect beauty; and Freddie, who despite being far from her U.S. home, finds strength in her friends. We forward to today, and as promised they are still firm friends . . . that is until a crisis occurs and the principles that define their friendship test are challenged. Exquisitely rendered by Elizabeth Noble, The Friendship Test is a powerful testament to the depth and capacity of female relationships.
