Heya Twig welcome to freedom! As far as our current lore we're in Draenor (Warlods of Draenor expansion), and we are soon to go to finish the garrison campaign, Blackrock Foundry, Highmaul, and then we will go to Tanaan all of which will take place after December/part way into Jan.
You can read up on the general lore on wowpedia, although if you like visuals/auditory I would recommend watching Nobbel87 videos.
