Ada Sibelius lives an unconventional childhood. She is raised by a single father, is home schooled, and her only friends are her dad’s colleagues at a computer lab at a prestigious Boston university. When she is twelve, as her father’s thinking becomes foggy and his memory fails, Ada, with the help of her father’s close friend, begins to live a more typical life. And when her father must go into a nursing home, she is forced to see that her father, David Sibelius, is not who he claims to be.
The Unseen World is an enjoyable read, for the most part. However, the ending left me flat. It was predictable, silly and self-conscious.
