"I need help," I whispered, not sure if I was talking to myself or to God. "I don't want to let her go." After her daughter was born, Kate Rademacher desperately wanted another child, but her husband did not. Following years of negotiation, the couple decided to become foster parents. What began as an uneasy compromise turned into an authentic calling and a deep love for their two-year-old foster daughter. When the girl transitioned back to her biological family, Kate thought she had learned the lesson in loving and letting go. But when an unexpected crisis occurred, Kate realized the lessons in how to love, accept, surrender, and forgive were only just beginning. In this poignant story, the author explores the question of where family begins and ends, and how things change when we invite strangers-with complicated stories and baggage-into our lives. For people who have considered becoming foster parents, many worry about the emotional risks involved. Before Rademacher's foster daughter arrived, she shared these concerns; she was deeply afraid of the heartbreak that seemed likely, and she worried that fostering could threaten her own family's peace. Rademacher's story is an insightful and ultimately hopeful examination of whether it's possible to love and let go without bitterness. With self-effacing humor and honesty, Rademacher describes how the experience of fostering impacted her marriage and her biological daughter and changed their lives forever.
