The Time Borrower

"It's always cold in Scotland. 1296 was not a good year for The Monastery at East Lothian, Scotland. Unexplained murders . . . sinister plots . . . and a 21st-century time traveler named Linna Sullivan who things she's fallen in love with a green-eyed monk. The only thing for certain is that she may be the next victim of a ruthless murderer.
Worse yet, an ex-boyfriend has followed her back into time, complicating the dangerous power struggle that has taken over the monastery. Most frightening of all is the battle that Linna faces when she must choose between the life she has known and the one that keeps pulling her into another century. Will she live long enough to make the right decision?"
