Eve and Sally meet when their lives as they knew them are ending— Eve fired from her thirty-year career, Sally walking out of a marriage of the same length. Enter Anastasia, a fiercely independent woman who lives aboard the narrowboat Number One and is facing her own possible ending. Anastasia needs urgent medical tests, but she also needs to transport her boat to the repair shop and back, a journey that will take weeks…weeks she might not have. So Sally and Eve find themselves aboard the Number One, facing challenges neither of them ever expected. The two fast friends navigate the canals of London, and discover that endings are often new beginnings.
