Just as good as volume 1
I love this series. There's always a slight concern with any series that there's going to be a nose-dive in quality at some point, but it certainly hasn't happened yet with 'Saga' - stunning artwork and a great storyline, with the in-laws turning up and complicating the ongoing negotiations between Alana and Marko about how their relationship is going to work in the outside world, with child in tow.
If you're enjoying 'Saga', I'd also recommend checking out 'Sex Criminals' (a decidedly not-traditional and somewhat adult-oriented comic series about folks who discover that they can stop time by having sex, which they then exploit for personal gain).
