I do love this one - a magical book gone wrong::

A Pirate's Life for Me by Addie Logan

http://spikeluver.com/SpuffyRealm/viewstory.php?sid=6739&warning=NC-17

Summary: As the Slayer, Buffy Summers is certain she hates the vampire Spike. But when an enchanted book pulls her into a world where she's Lady Elizabeth Summers, trapped on the ship of famed pirate William the Bloody, things start to look a little different...

Oh you just reminded me of another one!

A spell and a book gone wrong... I love this one!

Of fact and Fiction by Angel Eternal

Last one I swear (for now), LOL

Identity Crisis by SinisterChic

Spike does a spell to find out who he is, resulting in himself getting split up into 3 parts (epilogue NC17)

Replacement by sus WIP **I think this would fit at certain times with spells that should go wrong but don't work out the way they thought**

Broken Betrayal by Maryperk

I'd also check out her Double Dares and Magical Mixups

She has quite a few that fit this, but good for our couple not necessarily good for others.

And that's it my bed's a callin!

That oughta keep 'em reading for awhile anyway!

You think

Thanks, guys! Spikelissa, I think you can go to bed now, I don't want to be responsible for you being very sleepy!

SMac, I have seen A Pirate's Life For Me in so many threads and for some reason I always neglect to read it. So this is it, I'm really gonna read it this time!

Thanks for all of your quick work, everyone!
