Indeed it was! The story hooked me in from the get-go. Esme Lennox, of the title of the book, is the key character. She is a 70-something woman who has been kept in a mental institution in Edinburgh for 60 years. Her great-niece, Iris Lockhart, receives word that she is Esme's only remaining relative and is suddenly responsible for Esme, whom she never even knew existed before now. The mental institution is due to close and Iris has to make arrangements for Esme's further care.
Iris discovers that Esme was Iris's grandmother's younger sister. Iris's grandmother, Kathleen, who is in a nursing home with Alzheimer's, is no help in sorting out the mystery of why Esme was put in a mental home at the age of 16 and never released, never visited, never acknowledged as being a member of the family. As she learns more and more and gets to know Esme personally, she unearths long buried family secrets that have an enormous impact on her life.
This was a well-written story that moves along and is very hard to put down! The scenes of Esme and Kathleen's early childhood in colonial India and return to Scotland are well done - we can easily imagine the culture shock it must have been to move to such a different place for the two young girls. I also loved how the book not only focused on Esme, but is in fact the story of three women's lives: Kathleen and Iris are more than just side characters, the author's development of them adds great depth to the story and helps us understand more about the family and societal dynamics that led to the great tragedy of Esme's life.
Ultimately, this is a book about identity and how it is intertwined with our family and our ancestors as well as our descendants. As Esme realizes after she meets Iris:
We are all...just vessels through which identities pass: we are lent features, gestures, habits, and then we hand them on. Nothing is our own. We begin in the world as anagrams of our antecedents.
