I started reading The Dreamer
online (can't remember now precisely how I came across it) and fell in love with the story right from the start. Stories like this are one of my absolute favourite ways to learn about history. When IDW printed the first six issues I picked all of them up as they came out, and then my sister got me the collected graphic novel for Christmas.
The story is available online, which is wonderful, but having it in print allows you to see all sorts of little details that just get lost on even a really good computer screen.
