Sean has a business to run and Sheila is not good with groups. Effectively, Siobhan needs to supervise all the wedding preparations. The carousel is an unavoidable landmark. Siobhan organizes everything around it. The Merry-go-round Wedding becomes the social event of the year, with a front page article in a bridal magazine and news articles worldwide.
This is Siobhan's story. Events of HKMT occur in chapter's 7 through 11.
