Civil War

I want to read this Marvel Civil War deal, where good guys are fighting each other for some reason, and I am sure it is a good one, but it probably is some sort of moral question, or means to an end issue, but nevertheless I want it.

Anyone with a clue, can clue me in with a why and a who is on what team kinda thing. I am rooting for Cage's team. SWEET CHRISTMAS!

Art here by the way is that MichaelTurner fella from Image, then Marvel. This is his variant cover, which I dont like the idea of variants, because they serve no purpose. Below is regular cover artist Steve McNiven. I never liked Iron Man, and Cap was cool for a spell, but just too good all the time. Idealist usually die messy.

I will wait for the trade paperback. Aint they great.
