She is barely an adult when the trials of motherhood and marriage put her on an unexpected collision course with Jesus. After finding her faith at a suburban megachurch, Jamie trades in the easy life on the cul-de-sac for the green fields of Costa Rica. There, along with her family, she earnestly hopes to serve God and change lives. But faced with a yawning culture gap and persistent shortcomings in herself and her fellow workers, she soon loses confidence in the missionary enterprise and falls into a funk of cynicism and despair.

Nearly paralyzed by depression, yet still wanting to make a difference, she decides to tell the whole, disenchanted truth: Missionaries suck and our work makes no sense at all! From her sofa in Central America, she launches a renegade blog, Jamie the Very Worst Missionary, and against all odds wins a large and passionate following. Which leads her to see that maybe a "bad" missionary--awkward, doubtful, and vocal—is exactly what the world and the throngs of American do-gooders need.

    Not without difficulty, this boisterous, independent-minded teenager eventually adapted to the sisters’ austere life of poverty and devotion, but beneath the white-and-blue sari beat the heart of an ordinary young woman who faced daily the simple and profound struggles we all share, the same desires for love and connection. Eventually, after twenty years of service, Johnson left the church to find her own path, but her magnificently told story holds universal truths about the mysteries of faith and how a woman discovers herself.  Includes new material: Two reading group guides—for groups that wish to take different approaches to the book; a conversation between Mary Johnson and Mira Bartók, author of The Memory Palace; and Mary Johnson’s recommended reading list   “A wonderful achievement . . . Johnson opens the window on a horizon of spiritual questions [and] takes an unflinching look inside her own heart.”—The Christian Science Monitor  “An incredible coming-of-age story . . . [It] has everything a memoir needs: an inside look at a way of life that most of us will never see, a physical and emotional journey, and suspense.”—Slate “Reads like a novel . . . an exacting account of a woman growing into her own soul.”—More magazine   “Engaging, heartfelt and entertaining . . . [Johnson] articulates her struggles with her God in words that will hit home.”—Los Angeles Times   “An inspiration that transcends any particular religious belief . . . An Unquenchable Thirst is a journey that captivates, but its resonance lies in the life examined.”—The Denver Post
