The Highlander and the Sea Siren — Marguerite Kaye

When Lachlan Sinclair finds a naked young woman named Morven stranded on the shore of his Scottish isle, he is instantly drawn the beautiful being...and is surprised to discover that she feels the same burning desire that he does! Though Morven doesn't remember her home or family, she is sure of one thing: that she has come to be with Lachlan.

But despite their unbridled passion, both Morven and Lachlan fear for their future. For once Morven remembers who--and what--she is, she must decide if she wants to return home or make a new life with Lachlan...and their child.
