Thanks to everyone who commented on my last thread. Your comments assisted me to clarify my feelings about my novel. I've decided on a title, and it's none of the possibilities I listed.
Of all the responses, perhaps of most interest to me was the fact that no one picked Lily in the Valley, which was my working title for three years but which never satisfied me.
The other three titles were my attempts to replace it, but I didn't wholly like any of them either.
The new title, which I decided on this morning, feels absolutely right to me. It's one of those "know it in my bones" feelings.
This morning as I was walking Smokey, I was thinking about the most recent comments on the other post and, because of that, I was reviewing the themes of the book. Because of the tragic event that happened when she was 18, Lily lost her trust in God and she also shut down, giving up her professional hopes and her hopes of a loving marriage. One of the tensions of the first third of the novel is whether Lily will even allow herself to remember what happened--not in the sense of having amnesia but in the sense of forbidding herself to think about it or to even say the name of the boy she loved.
Two of the big themes of the novel are her journey back to God and her struggle to shake off the oppression of this past event. Two other significant details are that she was raised Catholic and she works as a translator.
So I was thinking of those two main themes and asking myself if anything in the novel could act as a symbol of one or both of them. And the answer came to me. There is a Catholic prayer that was significant in Lily's childhood and which helps her make her first tentative steps back to God.
The prayer is called the Memorare. It is a Latin word meaning "Remember." Faith and memory all in one word, which is a foreign word but that's appropriate for her character. And even for people who have no association with the prayer, the word looks enough like the English word memory to trigger that association. (Plus, the book is written in the first person and starts with Lily's decision to write down her memoir.)
So Memorare is my title. If I'm ever lucky enough to get this thing published, the publisher will quite possibly change it. But for now I have a title I really like and that is all that matters.
P.S. For those of you who have never heard of the prayer, here it is:
