Kate Atkinson and Karen Harris have written the book for Part of the Plan, which "follows three decades in the lives of an adopted boy and the teenage girl of privilege who was forced to give him up. Part of the Plan takes us through the boom times of post-World War II America, the social and sexual revolution of the 1960's, and the political upheaval of the 1970’s. It deals with themes of love, loss, friendship and fate - how everything is always part of a greater plan."

Fogelberg, who died in 2007, wrote such songs as "Same Auld Lang Syne," "Longer" and "Leader of the Band," among others.
