Your one & only / Finlay, Adrianne

"Jack is a walking fossil. The only human among a sea of clones. It's been hundreds of years since humanity died off in the slow plague, leaving the clones behind to carry on human existence. Over time they've perfected their genes, moving further away from the imperfections of humanity. But if they really are perfect, why did they create Jack? While Jack longs for acceptance, Althea-310 struggles with the feeling that she's different from her sisters. Her fascination with Jack doesn't help. As Althea and Jack's connection grows stronger, so does the threat to their lives. What will happen if they do the unthinkable and fall in love?"--Amazon.com.

In 2407, after the Slow Plague, humanity has ceased to exist--now, "homo factus," the Made Man, has taken over the planet, humans who have through genetic manipulation all but eliminated the imperfections of humanity. Into this world comes Althea-310, who was made to think and feel exactly what her sister Altheas think and feel--and Althea-310 feels she is different from her sisters. After a series of attacks rock their town, Althea-310 finds herself fascinated with Jack, the boy who may be the last genuine human on Earth, who is blamed for the attacks.
