Buffy travels back in time, meets, sleeps with Willaim

I'm looking for a fic which takes place in Season 4 when Spike is staying at Giles'. Buffy kills a Kronos demon, and there's a blast from the demon as it dies which propels Buffy into an alleyway in London where she runs into William, pre-siring. They go to a hunting lodge he owns, and find they are mutually attracted and make love. The time travel is temporary, and Buffy is pulled back to her own time, where Spike now has the memory of what happened between them in the past.

The Past Is a Different Country by randi2204.

Where can we find this fic?

Oops, it should be The Awakening by Sandy.
