I have just realized that I have been remiss in not mentioning that I just discovered and have been quite taken with The Dreamer, a webcomic which puts a high school girl from the present day smack in the middle of the events of the American Revolutionary War. It's painstakingly researched, beautifully drawn and colored, and has plenty of adventure, danger and romance as well as a healthy dash of humor. My only complaint now that I've caught up on all the archives is that I have to wait a week at a time to get the next two pages of the story!
However, it seems there is now a print version, for those who prefer a richer comic-book reading experience. Or you can read your way through the online archives, as I did.
Did I mention that Sarah Ellerton's currently running fantasy webcomic The Phoenix Requiem is brilliant and gorgeous as well? And that her previous comic opus Inverloch is now complete, all 764 pages of it? Yes. That.
