The book follows young Ruth from her arrival at the Kapi'olani Home for Girls in Honolulu, to her adoption by a Japanese couple who raise her on a strawberry and grape farm in California, her marriage and unjust internment at Manzanar Relocation Camp during World War II--and then, after the war, to the life-altering day when she receives a letter from a woman who says she is Ruth's birth mother, Rachel.
