On the idyllic island of Lute, every seventh summer, seven people die. No more, no less. Lute and its inhabitants are blessed, year after year, with good weather, good health, and good fortune. They live a happy, superior life, untouched by the war that rages all around them. So it's only fair that every seven years, on the day of the tithe, the island's gift is honored. Nina Treadway is new to The Day. A Florida girl by birth, she became a Lady through her marriage to Lord Treadway, whose family has long protected the island. Nina's heard about The Day, of course. Heard about the horrific tragedies, the lives lost, but she doesn't believe in it. It's all superstitious nonsense. Stories told to keep newcomers at bay and youngsters in line. Then The Day begins. And it's a day of nightmares, of grief, of reckoning. But it is also a day of community. Of survival and strength. Of love, at its most pure and untamed. When The Day ends, Nina--and Lute--will never be the same.
