After his father dies, Kai experiences all kinds of emotions: sadness, anger, fear, guilt. Sometimes they crash and mix together. Other times, there are no emotions at all—just flatness. As Kai and his family adjust to life without Dad, the waves still roll in. But with the help of friends and one another, they learn to cope—and, eventually, heal. A lyrical story about grieving for anyone encountering loss.

A brave, intimate, beautifully crafted memoir by a survivor of the tsunami that struck the Sri Lankan coast in 2004 and took her entire family. On December 26, Boxing Day, Sonali Deraniyagala, her English husband, her parents, her two young sons, and a close friend were ending Christmas vacation at the seaside resort of Yala on the south coast of Sri Lanka when a wave suddenly overtook them. She was only to learn later that this was a tsunami that devastated coastlines through Southeast Asia. When the water began to encroach closer to their hotel, they began to run, but in an instant, water engulfed them, Sonali was separated from her family, and all was lost. Sonali Deraniyagala has written an extraordinarily honest, utterly engrossing account of the surreal tragedy of a devastating event that all at once ended her life as she knew it and her journey since in search of understanding and redemption. It is also a remarkable portrait of a young family's life and what came before, with all the small moments and larger dreams that suddenly and irrevocably ended.
