Tranquillum House is a retreat that nine people have paid to go to to change their lives: weight, personal issues, etc. The main character is Frances, a romance author who needs to lose some weight, have her back made better and a huge paper cut seen to.
There are couples, families, singles who attend this particular session. The characters each have compelling stories about them.
Strange things go on at this retreat, engineered by Masha, Yao & Delilah, the staff working there. A lot of rather weird ideas about what helps people find their "true selves".
