The premise of this book is that the young Ada Silbelius is raised by her single father, a brilliant computer scientist. Until something happens. The characters are fully realized, haunting. I cried for about 35% of the book. There are secret codes. It’s partially set in the 1980s. I really loved this book.
Sadly, I can’t say anything more about it without giving away the entire mystery.
Another female author, another father/ daughter relationship. This time, Canadian.
