I'm sorry- HOW LONG??

I'm still on kingdom of ash, and I reached a point in Rowans POV: "Dorian and Aelin and Chaol now stood at a crossroads, merely a few miles from the salt mines. Where so much of this had begun, just over a year ago." So the ENTIRE series (maybe even assassins blade) took place over ONE YEAR????

it just- so much has happened- huh??? help me make it make sense because this really blew my mind
