If I'm reading Batgirl, am I going to be hopelessly lost in that issue? I have Birds, but the rest of my titles aren't really Bat related. If I get desperate, my husband has the Bat titles, but.

I don’t think you will be lost, I usually try my very best to make my crossover issues make sense on their own. There is a larger story, but I think you will definitely get the important elements if you just read the Batgirl issue OR if this is the only issue of batgirl you have read.

I do highly recommend the Batman issues at least, though, Scott Snyder is doingbrilliant work!
