Sex Criminals #9 (2013)

 A new key character is introduced and the majority of the comic is spent explaining her back story. Normally this can be a bit of a let down, I'm usually all about pushing the main storyline forward fast and furiously... but..

Mr. Kelly Sue Deconnick is such a good writer and seems to care enough about these characters that someone we never really knew is now just as interesting as the characters we've gotten to know over the past 15 months.

As always a comic you should be reading, though it should be sequentially (vol. 1 tpb is always in stock) otherwise you'd be lost jumping on here.
