Until I Wake — Elizabeth MacDonald

They met as children building a bridge of sticks over a creek in a Connecticut forest, united in the common need of friendship. When Addy's mother is accidentally murdered, Faith moves away, and they lose track of each other. Twenty years later they meet in New York City. Addy has published a children's book. Faith is a psychologist. Their secret pasts contain one common thread that may unwind their friendship. Can two women love the same man and remain friends?
