"Your One and Only" is an interesting young adult fiction. Adrianne Finlay has created a book about a young man who only exists in a world of clones. Jack is a strange being, because he tries to have some semblance of normal in the world he sees. I enjoyed reading about the clones, their habits, their mating rituals, their job choices, their decisions that they make in general. We also read through scientific journals about the clones, which provides a LOT of exposition, but I felt that it was necessary to understand more about the book and the characters.
We have a lot of fighting. Human vs. clone. We don't really have a lot of evidence why they are fighting other than "I don't like you because you're different". I'd love to see a sequel to see where we can go from there.
