It’s the end of the summer semester in Girton College and Winifred has a new room-mate. They don’t have much to do with one another until the day Winifred arrives back unexpectedly, and finds Rachel in a compromising position.
There are two sides to Winifred Churchill, to the public she is an up-and-coming "investigating journalist", but in her private life she just loves sex, and she's doesn't mind if her partners are male or female. Victorian's didn't hate sex, they loved it in all its forms.
These books take place in an alternative Victorian timeline.
