Time and Again — Anna Leigh Keaton

Therese Whitmore is a realist, a historian, and the Smithsonian's expert document preservationist hired to perform a job for a wealthy Scotsman. She doesn't believe in the nonsense of past lives.

But when she arrives at Camden MacGregor's castle, it feels like home, his touch makes her tingle like no other, and when she reads his family's ancient journals, she experiences déjà vu like nothing she's ever known.

Camden knows his long search is over. He's found his soul mate, but trying to convince Therese…when she has no memory of her past lives…might cause him to lose her forever.
