I can't remember the name of this book ! I'm looking for a book which I think is from from the 80s or possibly early 90s ? It's about a woman who desperately wants a baby and so she ends up meeting a strange man and makes a deal with a strange guy ( demon ?) to have a baby . As part of the deal she gets pregnant with twins and is supposed to give 1 away to the strange guy ? (demon ? ) She finds out that other women have made the same deal and that the other twin babies have miserable lives ? So she struggles to find a way to keep both babies.
