In Sequart's Moving Target: The History and Evolution of Green Arrow, Richard Gray paints a complete picture of DC Comics' battling bowman, from the Golden Age to the New52 (not forgetting the Arrow show), with a few key creator interviews along the way. He loves his subject, that's clear, and perhaps he fawn over it a bit much sometimes, but his thesis that Oliver Queen is a "moving target", continually moving from one incarnation to another with the whims of continuity is an interesting one. Though he's working with 75 years of history, Gray finds a nimble enough thru-line for the character. There are a few errors in the book, but they're never about G.A. himself and like the occasional typo, don't really detract from the work. I like Green Arrow, but I admit to having skipped a lot of his comics, so I definitely learned something. Moreover, I was impressed enough to wish other writers would take up the baton and provide Sequart with similar books about the second string of superheroes - like Hawkman & Hawkwoman, the Atom, or Supergirl.
