If anybody is interested in webcomics, I can only recommend, ever so much
The Dreamer, by Lora Innes.
It's a comic about a normal Boston High School girl who at nights finds herself in the American War of Independence/Revolutionary War, surrounded by historical figures such as Nathan Hale or Thomas Knowlton.
At first it's fun, and she enjoys the attentions of the dashing Major Alan Warren, but soon the fact that it's a war becomes real, plus Bea begins to have doubts which time is the real time, and her 18th century (dream) experiences begin to overshadow her 21st century life.
It's full of excitement, romance, history geek-ism, the works and currently updates twice a week - go read! The artwork is getting better and better too, which makes many of the pages with the historic costumes and all look a real treat.
I can't precisely say much about the whole time-travel there though, since so far, it's not even clear if it's time-travel that is happening to Bea Whaley - and there are a lot of theories around as to what is happening to her, and which time is 'real' - but I'm sure that if it is, there's gonna be one heck of an explanation for it!
