The story of the son of Adam Black!

Book not available in French, so I tried in English.
This is the story of the son of Adam Black that are found in many books by Karen Marie Moning.
Besides, there is a reference to the story in "The Black Adam punishment."
The story is set in the past, but a woman of the future, Lisa, finds himself catapulted into this time Scottish warriors.
All the right ingredients are in: suspense, love, humor, and past-future interaction!
It is a pity that we do not find this book translated into French because it's really worth.
