I'm assuming it has TBPs for me to get caught up, or is it a recent startup? Will check.
The series stared ~2011 if I remember correctly, and it just finished this year. Yes, there are individual TPBs that collect several issues at time, but the omnibus just came out which collects all of the issues (42). Had I not already started getting the TPBs, I'd get the omnibus. It's a monster at 900-ish pages! Terry Moore sells the omnibus from his website, but your LCS may also carry it.

Ordered the omnibus from instocktrades.... previewed the art on youtube and looks interesting...thanks! At .05 per page the omnibus feels like a great bargain.
Awesome, let us know how you like it!
