Set in London, this is a cute, flowery tale of a young florist falling in and out of love. The main character is Abby Crompton, a naive commoner engaged to marry the son of a royal English lady. But something is missing from Abby's relationship with Toby Kenwood, and it is more than the engagement ring he did not produce when he proposed.

Abby is suspicious Toby might be gay. She raises the question to him, and he adamantly defends his heterosexuality. She drops it until she catches Toby on a date with a man when he was supposed to be working out of town. She breaks off the relationship and is devastated.

Soon Abby starts dating Dan Chipault, even though she is not over the hurt of being betrayed by Toby. She met Dan when the two were trapped in an elevator, but coincidentally he was the producer of a movie for which he was planning to film a scene in Abby's shop. Jealousy and distrust plague Abby almost to the detriment of her new relationship.

The author tells the story using simple dialogue, making "Forget Me Knot" a quick and easy summer read. Several conflicts in the fringes of the main characters' lives keep the book moving.
