Books in Crosstime Traffic series

In Harry Turtledove's The Disunited States of America, Justin's having the worst trip ever. He and his mother are Time Traders, traveling undercover to different alternate realities of Earth so they can take valuable resources back to their own timeline. In some of these worlds, Germany won World War I or the world has been destroyed by nuclear warfare. Justin and his mother are in an America that never became the United States: each state is like a country, and many of them are at war with each other. Their mission takes them to Virginia, which is on the verge of bloody violence with Ohio. Beckie is from California, and like the rest of her world, unaware that Time Traders exist. The only reason she's in small town Virginia is because her grandmother dragged her there to visit old relatives. Beckie is just as horrified by the violence and racism of the alternate Virginia as Justin is, and the two are drawn to one another. But when full-fledged war breaks out between the States, including a biologically designed plague, will either of them manage to get back home? Forget about home: Will they make it out alive?

Time travel doesn't work. You can't go backward or forward; you're stuck at "now". What you can do is travel sideways, to the same "now" in another timeline where history turned out differently. So far, only our home timeline has figured out how to do that. We use it to conduct discreet trading operations in less advanced timelines, selling goods just a little bit better than the locals can make. It's profitable, but families who work as Time Traders have to be careful to fit in, lest the locals become suspicious. Justin's family are Time Traders. The summer before he's due to start college, he goes with them to a different Virginia, in a timeline where the American states never became a single country, and American history has consisted of a series of small wars. Despite his unease, he accompanies Randolph Brooks, another Time Trader, on a visit to the tiny upland town of Elizabeth, Virginia. He'll only be away from his parents for a few days. Beckie Royer thanks her stars that she's from California, the most prosperous and advanced country in North America. But just now she's in Virginia with her grandmother, who wants to revisit the tiny mountain town where she grew up. The only interesting thing there is a boy named Justin--and he'll be gone soon. Then war between Virginia and Ohio breaks out anew. Ohio sets a tailored virus loose on Virginia. Virginia swiftly imposes a quarantine, trapping Beckie and Justin and Randolph Brooks in Elizabeth. Even Crosstime Traffic can't help. All the three of them can do is watch as plague and violence take over the town. It's nothing new in history, not in this timeline or any other. It's part of the human condition. And just now, this part of the human condition sucks.
