I also try and support the female led books when it's a character I really like. I've been reading the JiM featuring Lady Sif and found it to be average at best. I've not brought it up cause of that. It's a book that right now I could drop if I found something that really impressed me. DC just cancelled FRANK Agent of SHADE so Lady Sif remains safe.
I do like Red She Hulk, that book has been a fun read if you're so inclined.
I'll probably get Fearless Defenders
when it comes out
