Please help me find this book! Time travel medieval romance from the 90's (I think)

I've been searching for a book for many years now. My nan lost it on me and I've been searching here, there and everywhere since.

The author was Susan Longsword, not sure on the author's real name though this pen name turns up no results. The cover has a jewelled dagger on it set on a cream coloured background.

While I can see scenes here and there in my mind there isn't enough of it left in my mind to give you a better description than the following:

All I can tell you is that it was a science-meets-time-travel-to-the-middle-ages type of romance book. The lead male was called Dafydd De Jorgen - the rake (david the wolf). A man goes back in time to search for his female colleague that was sent back for research though hadn't returned when they expected her to etc. I believe it's set in medieval france. It was such a gripping story for just a cheapie romance novel I found in an airport lounge while waiting for a flight. I'd so dearly love to get another copy!

Some of this seems to match Wings of the Storm by Susan Sizemore. Time Travel, guy named Daffyd, error in where she landed, at least from what I could google.

I'm pretty sure Scorbet is right on this and it's Wings of the Storm - it's more common with a typical 'romancy' cover, which might have made things difficult for you, and the 'rake' is Daffyd ap Bleddyn but I managed to find a version that looks like it matches the cover you remember:



If you really loved it, there is a sequel too - After the Storm.

Thank you (the the poster below) ever so much! I'm absolutely chuffed to bits! It's been so long since I've read it, this is just wonderful!

Not sure where I got Susan Longsword from, hah!

A sequel! Oh my, and I thought finally finding out the name of the book was amazing - but there is a sequel! Thanks so much for letting me know woohoo!
