Knowing Me — Evelyn Hood

Another superb saga from Sunday Times bestselling author Evelyn Hood. Rachel Carswell is at her father's funeral when she learns she's adopted, news that shakes her formerly serene life to the very core. Confused by the revelation and devastated by grief, Rachel needs a distraction. Much against the wishes of her husband and her adoptive mother, she starts the search for her roots and discovers she has a twin sister, Clara. Cara is the woman Rachel could have been, given a different upbringing. While Rachel's staid husband and her adoptive mother, try to cope with the sudden intrusion of Cara and her easy-going, attractive husband Angus into their lives, Rachel and Cara search for their biological mother.
