This was a nice, quick and decent read. The heroine is a wealthy heiress who discovers that she has a lot of biological siblings out there and hires the hero to find out where they are. The heroine is shown as a cautious sort, her parents wealth attracted all the crazies, a kidnapper, people who wanted to use her and that has made her adopt an ice-cold persona. The hero fights to make her put down her barriers. I did feel the heroine held on to her doubts for way too long though.
