Dominion [PDF ebook] 

From the creator of 52 and ANNIHILATION, Keith Giffen! An alien microbe, traveling through space, arrives on Earth and discovers humanity. As it enters an array of innocent human bodies, it remakes them into something new, something powerful, but, most ominously, something wanting its own homeland — its own dominion. This trade paperback collects the critically acclaimed mini-series showing the battle between ordinary humans and this new, alien invader that takes over mortal bodies and infuses them with untold power!
