I am looking for a SessKag story that I had read about a year ago. It's about Kagome and her gang being summoned by the Western Lady to help in war against the cat demons. When they get there, the Western Lady is very taken with Kagome, amused by Kagome's and Sesshoumaru's behavior towards each other, and she orders Sesshoumaru to mate her. After the mating ceremony, complications ensue- the Kamis do not like the union(though they do initially give their consent)- and one of them is a traitor and is in league with a dog demoness who is furious with the mating and thinks that Sesshoumaru belongs to her. She is discovered to have had his son, who is actually an impersonator. SessKag's mating seems to be doomed, and things get further complicated when Kagome is discovered to be pregnant. Meanwhile, Inuyasha flees, joins up with Kikyo, and has sinister plans for the pair as well...
If you know what story this is, PLEASE, send me a PM and let me know! I will be in your debt! Thank you so much :)
UPDATE: Found it! It's called THE BATTLE OF HEART AND LAND by MissKatt18! Thank you so much to those of you that responded and guided me in the right direction, you're AWESOME! :)
