Being a huge fan of Chelsea Cain's "Heartsick" series, I was confused and perplexed yet incredibly excited to see her venture into the comic book realm. I'll openly admit that I haven't read much of Mockingbird beyond her appearances in Hawkeye serializations and Agents of SHIELD, but Cain has managed to put a new, intriguing twist on an old-age character (plus a much better fashion upgrade.)
The overall plot is nothing significantly groundbreaking, but it's given a fresh perspective of what has otherwise been a fairly mediocre character. Cain's storytelling is fresh, perfectly balancing a light-hearted nature with serious issues (Bobbi's struggle with depression and the futility of controlling her life) to offer young comic book readers a fun read.
There's laughs, there's corgis, there's speedos, and there's bdsm clubs.
Anyone that was impressed by the New 52 Catwoman's blatantly owning her sexuality will find that Mockingbird does just that in a more muted, less scandalous manner. I look forward to seeing what all Cain has to offer in this new format.
