Dear 100 Hour Board~
I need help figuring out the title of a book: it is about a group of people getting to choose their bodies before they are born. Two of them are in love with each other. Another is in love with a man, who has already been born, so she wants to take a body that will only live for 15 hours in order to meet her soon-to-die man in the afterlife.
The book title starts with an "S" and is one word -- some word I've never heard other than in this title (Sarillian? Something like that). The process of taking a body is called "enclayment." I believe the author is a female and has three names on the cover. That's everything I know. I've done online searches and cannot find anything. Can anyone tell me what the book is called?
