ABANDONED. Book about women stuck in an elevator they all plot to kill someone they don't know once they leave

[Laraina]

I read a story a few years back about four of five women who got stuck in an elevator. While in the elevator the women talked about people in their lives they wanted dead. They each wrote the name of the person on a sheet of paper and one paper was blank. The ladies drew names. The name they chose was the person they had to kill. One person did not have to kill anyone. They did not know who had which name.

Sounds like Getting Hers by Donna Hill - and a variation on Strangers on a Train.

Rai, was "Getting Hers" your book?
