From the gift box of books I grabbed this one, not entirely at random--it was the largest book in the box, in part because it is hardcover.
It has an interesting approach to a concept of a multiverse, with a few interesting twists. Two of those twists are characters; the third is in the title "Resonance", which refers to the tendency that anything that happens in one universe is increasingly likely to happen in another, increasing the probability that it will happen in others; some events thus become inevitable.
The main character, Graham Smith, is an anomaly, the only person who exists in every known universe, due apparently to a previous resonance; he has the problem that his consciousness jumps from universe to universe, but he does not understand it that way--he perceives it as the universe unraveling, changing constantly around him, and he does not understand why no one else ever talks about those changes, but he tries to keep quiet and talk about nothing at all as buildings, roads, even people vanish and reappear seemingly at random. He keeps a note in his pocket telling him where he lives and where he works, and checks it regularly to see if the information has changed.
The girl, Analise Mercado, is also interesting--the unknowing product of a genetic experiment that was supposed to make her telepathic, she hears the voices of parallel selves in her head, and can communicate with them. Each of her selves is seeking an explanation for this.
A company which has found a way to collect information from parallel dimensions has become interested in both of them, and as a result they come together--but someone wants to eliminate his ability, and no one knows who or why. She has agreed with her selves to protect him, working with whatever allies they can find, but even that is difficult as some of the people most able to help them in one world don't exist in another.
It also becomes evident that the Grahams and the Analises of various worlds are different, and the Graham who becomes the primary protagonist falls in love with one particular one, in one particular universe, from whom he is separated; he seeks a way to return to her as well as prevent the disastrous futures he has witnessed on some of the worlds that are technologically ahead of the curve but growing more certain.
The book has a slow start. It tries to paint the picture of the ordinary life of a character whose life is anything but ordinary, and in doing so it creates the puzzle; but it took a while to grab me. Once the story was in motion, it was good reading, with lots of questions, some serious issues, tensions about possible outcomes, and a good dose of action and suspense. Chris Dolley manages to pull a happy ending from the complications, and keeps us on the edge of uncertainty as to whether it is going to work out for the characters or not.
It was an interesting concept fairly well executed. It's not a book that begs me to share it with anyone else, but I will probably keep it around and read it again sometime.
