There's a whole range of comics catering to those more esoteric (and often quite boring, frankly) storylines, and a good many of them have books for sale.
Check out Something Positive (terrible people), Stand Still, Stay Silent (kid friendly but a little dark, beautiful art), Dumbing of Age (ugh, but some people like it), Vattu (kid friendly, nice art, coming-of-age), Schlock Mercenary (goofy, sometimes a little mature but kid friendly), Gunnerkrigg Court (female protagonists), or any of several other dozens. All of those have books out, I believe, except for maybe SSSS.
EDIT:
Something Positive is probably the best-written webcomic out there today, with the best characters and dialog and plot--it's only flaw is that it might be a bit raw and inaccessible to people younger than teenagers (the first strip being a mean abortion joke probably doesn't help).
I think Dumbing of Age is targeted at people who are post-college, not kids. A lot of the humor and depth is most manifest to people who have gone through similar crap and can look back on it nostalgically.
