Historical Romance: hero & heroine are on ship together and hero is help captive heading somewhere and becomes friends with heroine

[Brooke]

Hero cannot see the heroine, only her feet so he thinks shes a plain Jane.

Pretty sure heroine is blonde and on the front of the cover.
I think the book was written in the 90s or early 00s.
