Kat’s Pride (2013)

Blurb:
Wealthy socialite Kat Balfour boards a gorgeous yacht for a Mediterranean cruise at her father’s recommendation. However, it quickly becomes clear, from her tiny accommodations and the big pile of responsibilities, that she’s here for work, not pleasure. The yacht’s owner turns out to be the man she so haughtily rejected at a charity ball—successful businessman and former matador Carlos Guerrero. Kat learns that her father set her up on this trip to teach her responsibility. And Carlos proves a relentless taskmaster . . .
