Attack on Titan, Volume 5

You're finally introduced to the members of the Survey Corps! I think Zoe Hange has to be my favorite character so far. Her obsession with learning and her willingness to talk anyone's ear off about the subject she loves most reminds me a lot of myself. Her short (for the reader at least) conversation with Eren gives some new information about the titans. Despite it being WAY past my self-appointed bedtime, the cliffhanger at the end had me snatching up the next volume in an instant!
