When twenty-seven-year-old Joan Bergstrom sends a fan letter—as well as a gift of saffron—to fifty-nine-year-old Imogen Fortier, a life-changing friendship begins. Joan lives in Los Angeles and is just starting out as a writer for the newspaper food pages. Imogen lives on Camano Island outside Seattle, writing a monthly column for a Pacific Northwest magazine, and while she can hunt elk and dig for clams, she's never tasted fresh garlic—exotic fare in the Northwest of the sixties. As the two women commune through their letters, they build a closeness that sustains them through the Cuban Missile Crisis, the assassination of President Kennedy, and the unexpected in their own lives. Because of her correspondence with Joan, Imogen's decades-long marriage blossoms into something new and exciting, and in turn, Joan learns that true love does not always come in the form we expect it to. Into this beautiful, intimate world comes the ultimate test of Joan and Imogen's friendship—a test that summons their unconditional trust in each other.
