The Sheik's Missing Bride — Elizabeth Lennox

Sarila ran away six years ago, determined to avoid an arranged marriage. So how had he found her so easily? No problem - she would simply run away - she could disappear once again. So run she tries - right into her betrothed.

He makes a deal with her - two weeks with him on his ship - during which time they prove to their parents that they simply don't suit.

Except...they find that they do.
