I like Misconceptions And Misunderstandings by Time on my hands. Kagome is somewhat broken in the first chapter but after that she gets her fire back. It starts out a little angsty but it has a happy ending. I highly recommend it.
Misconceptions and Misunderstandings
Without caring for the facts, Sesshoumaru jumps to the wrong conclusion with devastating results. Now months later, armed with the truth, he has to find a way to right the wrong or forever lose any hope of happiness.
Rated MA
and if you like one that has both the past and the future there is
Midnight meets Moonlight by Mujitsu
Midnight Meets Moonlight
(1st place winner in Best Romance and 1st place of Best Kagome Portrayal on A Single Spark! Thank you to who voted!) Kagome meets a present day Sesshoumaru and goes back to the Sengoku Jidai, only to meet the formidable TaiYoukai there. Can romance happen? Rated M for swearing and content in later chapters...
Rated NC-17
Ghosts by RosieB
A nine-part response to the Dokuga LJ comm\'s Child\'s Play Challenge. After Naraku\'s death, Kagome returns to her time forever, where she mourns her losses. An older Sesshoumaru offers a deal - a comfortable and secure marriage in return for a child. After all, they\'ll never love anyone - including each other - again, right?
Rated T
On the story "Ghosts" it says that you don't have to read the one-shot "My Obligation" from her collection "The Crickets Cage" but I found that parts of the story made a little more sense after I did.
