Prologue

June 2011

Dawn sat looking out the window of hers and Willow's home on the outskirts of London looking at the wintery landscape as she thought back on the years after the battle of Sunnydale.

There had been of course the double wedding on her birthday where she had married Willow and Buffy had married Faith.

She had gotten her Bachelor's, Master's and Doctorate degrees over the eight years after the Battle of Sunnydale.

She smiled as she thought about her goddaughter Jessica. Anya had given birth during after that final battle.

"What are you thinking about?"

Dawn turned to see Willow standing in the doorway leading toward the kitchen. She smiled at Willow as she crossed the room and pulled her beloved into an embrace and kissed her passionately. "Just all that has happened since the Battle of Sunnydale."

"I know what you mean," Willow replied, "especially with what happened last year."

Dawn thought back and nodded in agreement. Buffy and Faith had decided they wanted a child. But neither of them wanted some unknown person for the father. That left only three guys they trusted for the job; Oz, Xander and Giles. Oz had long since married to a female werewolf in Tibet and had two children, both of whom had inherited the werewolf genes from their parents. While Oz told them he had been happy they had thought of him, he had to decline. Seeing how Buffy and Faith would have to restrain their child on the nights of the full moon.

So Buffy and Faith had approached Giles, who also declined. He had always seen himself as the patriarch of the group which meant that Buffy, Dawn, Faith, Willow, Anya, Xander and all the other former Scoobies had been his children in all but blood and he was happy for it to remain that way.

That left Xander. At first Anya was against it, but Xander somehow managed to sway her and she consented. So Xander became the father to Buffy and Faith's daughter who had been born earlier in the year.

"You're right of course," Dawn told Willow. "You know I never figured Xander would be the one to father Joyce."

"But he did, and he is a good man," Willow said. "I know that from experience, after all I've known him for twenty-three years. "

Just then a letter flew through the mail slot and landed on floor by the front door as Dawn went over and picked it up. "Will, it's addressed to you," she told her lover.

Willow walked over to Dawn, who handed her the letter. She opened and began to read.

Dear Mrs. Willow Danielle Rosenberg-Summers nee Evans,
