Blankets is super sad and really well done. If you liked that you should read Asterios Polyp and Essex County. Both were fantastic works of fiction done in comic form.
If y'all like intense action and/or historical comics, check out the Northlanders series. They have short storylines (7 to 10 issues per story) about vikings and other cultures in the nordic areas during the early 1000s. They're wild and ranging stories and would appeal to anyone who liked the movie Valhalla Rising.
