This story is full of flashbacks into what appear to be the past lives of the 2 present day characters.
They meet – in a way that both of them could not explain their action because they felt pulled to the town they meet in. Abby is an author and Quinn runs a antique shop. Abby finds a box of old photos in the shop and is drawn to one in particular. She takes this and uses it as inspiration for her next book. She writes the story of the 2 women in the photo – a story that just comes to her as she looks at the photo. She is then amazed to find that what she wrote was true – even down to their names.
Abby and Quinn both have visions of the women and also other women couples going back to 1507.
This is well written as flashbacks, with all of the lives becoming entangled as they were essentially the same people reincarnated looking for each other through time.
It was an intriguing story, made more interesting by the different time periods, attitudes towards same sex relationships and a fictional insight into lesbian life in those times.

There is of course an epilogue.
This is set 2 years after the story ends and sees Abby and Quinn buying the house the photos had come from and therefore living in the home of their previous incarnations. The book is written.
