The Long Way Home, which I got from the Miami-Dade Public Library via Columbia interlibrary loan, takes up where the tv show leaves off, more or less. So far having read the first and third installment, I haven't really learned much about what happened immediately after the destruction of the hellmouth and Sunnydale, just that Buffy, the surviving Scoobies, and the potentials have relocated to Europe. And that somehow along the way, Dawn got turned into a giant, which is possibly some kind of mystical STD.
Like Wolves at the Gate, The Long Way Home retains the show's voice and characterizations, but the drawings look a lot less like the actors, which I guess is strange because it's the same artist. I found this one a little harder to follow, as well. The scenes switch back and forth, sometimes from dream to reality, as well. I'm not an accomplished comics reader, though, so don't take my word for much.
