Cape Horn: One Man's Dream, One Woman's Nightmare
I know the woman that wrote this book and her husband. I think it is a GREAT read and I was totally into their story.
For your wife, however, I think it would invoke too much of the scary parts
of cruising. Pitchpoling your boat and having all of your earthly possessions turned upside down soaking in 40 degree salt water
is probably over the top.
I do think however, that the message of the book, is that she triumphed over her fears and was somehow stronger after the ordeal.
