This isn't really a romance novel - for you young people, this is an extinct breed.  It's an airport book.  It's about rich people doing awful rich people things and it never forgets to mention a brand name.  It's about Poor Little Rich Girl Elizabeth whose father seems to have accidentally set up a tontine in the family business - only one of her cousins is actually trying to murder her but honestly, they all want to and it might as well have been any of them so does it really matter which one it is?
