Crosstime Traffic is Harry Turtledove’s young adult series, and it has a clever setup. In the near future, a company has discovered how to travel between alternate timelines, and they send traders to parallel worlds to buy resources. When things go wrong, teenagers from our timeline have to survive in worlds where history took very different turns.

Each of the six books is set in a different alternate timeline, from a world where Rome never fell to one where the United States split apart. Published between 2003 and 2008, the series is a good entry point for younger readers interested in alternate history.
