“Only humans can hurt one another, Ada thought; only humans falter and betray one another with a stunning, fearsome frequency… She would fail other people throughout her life, inevitably, even those she loved best.”
Ada’s father David is the most important thing to her. For thirteen years David has been her teacher, her best friend, her guide. Ada’s life has revolved entirely around him and his work in his computer science lab, so when David begins to forget things and disappear for hours at a time, Ada’s world as she knows it rapidly changes. As David’s mind disintegrates, Ada must navigate the coming years without him. Life grows more complicated as she moves in with her father’s long time friend, and evidence surfaces that David may not be the person she thinks he is.
I think the experience of admiring and idolizing a parent and then gradually realizing that parents are fallible human beings is something to which everyone can relate. The reverence with which Ada views her father is so powerful that it’s easy to feel the confusion, frustration, and protectiveness that Ada feels when her father’s health begins to decline. The relationship between father and daughter is the foundation of the story, and the author does a wonderful job of portraying some of the complexities of that relationship.
The characters are clearly written and consistent, their actions aligning with their personalities so the interpersonal dynamics work well and were convincing. The last third of the book felt a less cohesive for me during the jumps in time back and forth to Ada’s adulthood. I didn’t connect as strongly to the older Ada as I did to the younger one, but perhaps that that’s because we spend less time with her in her adulthood than in her youth.
Still, I liked this book much more than I anticipated. The pacing was consistent through most of the book, and the cryptology as well as the mystery surrounding David’s history and eccentricity kept me interested. As the beginning of the story unfolded, I had so many questions about Ada and her upbringing. I felt like I was slowly turning these small corners, each one revealing another piece of the puzzle, which kept me wanting to keep going along with Ada as things began to unravel.
4 out of 5 stars
