Amy S. Foster is a Canadian songwriter and author. She is the daughter of record producer and songwriter David Foster and Bonnie Jean Cook.
Best known for her collaborations with Michael Bublé, Foster has co-written "Home", "Everything", "Hold On", "Just Haven't Met You Yet", To Be Loved, and "Beautiful Day". Her songs have also been cut by Blake Shelton, Destiny's Child, Josh Groban and Andrea Bocelli. Foster states that when Bublé sent her an early draft of Home her first thoughts were, "Oh, great, complain about being stuck in Europe," nevertheless, she related to the idea of missing someone, and agreed to help write the song.
Her first book, When Autumn Leaves, was published in 2009. The reviewer in Booklist wrote that, "the romantic, mystical setting and appealing characters will delight readers searching for a modern-day fairy tale."
