Retired Episcopal priest Earle Martin has a new mission in life: to share with the world the lessons he’s learned from his autistic grandson, Charlie.

Martin’s new book, “The Boy Who Saved My Life,” is a story of love and redemption that will inspire readers to reach out and experience a life-changing relationship with a special person. Without ignoring the undeniable challenges, “The Boy Who Saved My Life” illustrates how opening ourselves to those with special needs can bring immeasurable gifts to us. By sharing his story, Martin hopes to introduce the reader to special needs children and adults in a way that encourages involvement with them and can lead to transforming love, wisdom and inspiration.

Martin will discuss his book at the First Presbyterian Church of Lake Forest, 700 N. Sheridan Rd., on Tues., Oct. 2 at 10 a.m. A question and answer session and book signing will follow. Martin will also hold a book signing on Mon., Oct. 1 at 7 p.m. at The Bookstall at Chestnut Court, 811 Elm St. in Winnetka.
