I try to imagine myself learning, at age 52, that I have a sister. I think about my own sister and how important that relationship is to me. I think about how much life there is in 52 years — how much identity is formed, how awkward it becomes just making friends as an adult — and I canโ€™t imagine it. Surely it would be confusing and scary and thrilling, but what would that even mean?

This is the premise of Katherine Linn Caireโ€™s memoir, Accidental Sisters: The Story of My 52-Year Wait to Meet My Biological Sibling (Books Fluent). A self-proclaimed happy adoptee from Des Moines, Kathe — who was heretofore uninterested in anything to do with her biological lineage — decides in her 50s that she should look into getting medical records for her own children.

(She says, โ€œ[E]xperience showed me that if children were not happy with their adoptive parents or their family life in general, they would be more likely to seek their birth mothers โ€ฆ This was my myopic view of adoption as a child growing up with adoptive parents.โ€ She recants this idea a few times, aware of the privilege and naivete of this take.)

Katheโ€™s story is full of fateful moments, the first of which is her sudden impulse to procure a medical history for her children. โ€œI found myself staring out the window into our very dark, quiet front yard and suddenly the thought came to me: our precious three daughters were approaching โ€ฆ adulthood, and they only had exposure to 50 percent of their medical history.โ€

Divine intervention is a prominent theme, which is fitting for a story that started with a Catholic girl in a Catholic hospital giving up a child for adoption at Catholic Charities. Religion itself is not a major theme, though religion did connect the biological family to the adopted family. These instances are catalysts for near-misses and odds-defying revelations for Kathe. โ€œ[B]y that point in my life I knew that ideas that โ€˜come out of nowhereโ€™ tend to have a distinct purpose,โ€ she said.

The narrative is chronological, almost entirely exposition, and starts with Katheโ€™s adoption, including her parentsโ€™ application letters to the adoption agency. There are anecdotes about her early childhood and then her search for medical information. Itโ€™s an error in the redaction of one of the documents Kathe receives which sets off her journey to learn more about her biological mother and, eventually, to meeting her sister.

Katheโ€™s story includes watching her parents age, receiving the support of her family, extreme moments of synchronicity and a lot of introspection and exploration of her birth motherโ€™s experience.

While the bookโ€™s subtitle assumes the climax of the narrative would be the meeting of two estranged sisters (and I would say that it is), that meeting is about halfway through the memoir, and is followed by further odd surprises from research, building the relationship between the sisters and cultivating a spiritual connection with the Maurer family. (Maurer being her biological motherโ€™s maiden name.) Katheโ€™s journey (and her sisterโ€™s) are not that of self-discovery, but of an ongoing quest to learn oneโ€™s self.
