This would have been around the mid-2000s, with the book having been published fairly recently at the time I read it. It was in a school library, so probably leaning towards YA.

The plot, as I recall, was that a group of people had travelled back in time to the then-present, trying to avert the bad future they came from that featured an oppressed underclass of clones. I think one of them was called Anti Clone? They succeeded by encouraging someone in the present to pursue physics and develop fusion power, whereas in the original timeline he was the inventor of the cloning technology.

  • Hi, welcome to SF&F. Do you happen to have any recollection of the cover?

Could this be The Bradbury Report by Steven Polansky?

It is 2071. A cloning program provides spare organs for the healthcare system. An unlikely candidate for adventure, Ray is a man in his sixties, who gets a call out of the blue from ex-girlfriend Anna. Now a political activist, she asks for his help to hide an escaped clone. The escapee is none other than his own clone.
