As much as massive universe-altering crossovers get criticized, I loved The Question storyline throughout the weekly 52 event a few years back. It treated Vic Sage with real love and respect, and made his successor take on the role in a very natural manner. The Question: Pipeline is a collection of what I assume were back-up strips from the pages of Detective Comics featuring Renee Montoya as The Question. The book begins with Montoya still working with Professor Rodor and running a hotline where people who have problems can call in for help. One such call sets Montoya looking for a missing illegal immigrant, and soon the missing woman's trail leads to a massive world-wide smuggling operation. The first half of the book is the best, full of exciting action scenes and with a nice conclusion. The serialized nature of the short strips makes for a lot of cliffhangers, but it works well. The second half of the book continues with Montoya on the trail of the mastermind behind the smuggling ring, but is a little bit more of a standard superhero book. Montoya teams up with The Huntress to take on the super-villain who is behind everything. The comic implies that the villain created the whole smuggling ring just to lure Montoya into his grasp for revenge, but that doesn't make a lot of sense (nor do other motivations behind the villains' actions). So overall, somewhat uneven; but if you're a fan of The Question, it's working picking up.
And I have no idea what the character is up to, if anything at all, in the rebooted continuity . . .
