It could be about many things. Maybe it's about a family's hidden past that is full of mystery and darkness. For example, it might involve secrets like long - forgotten family feuds, or a crime committed by a family member years ago that has been covered up.
I'm not sure specifically as there could be many novels with that title. It might be about a deep, hidden mystery or a character's very private and disturbing secret.

The title 'the deepest secret a novel' is quite intriguing. It makes me think that this novel might be centered around a secret that is not only difficult to discover but also has profound implications for the characters. It could be a psychological exploration of how people keep secrets, how they are affected by them, and what happens when those secrets are finally revealed. The 'deepest' part might suggest that it goes to the very core of the characters' beings or the fabric of the story's world. There could be themes of guilt, redemption, or self - discovery related to this secret as well.
One of the darkest children's stories is 'The Little Match Girl' by Hans Christian Andersen. The girl endures extreme cold and hunger while trying to sell matches on a freezing New Year's Eve, and in the end, she freezes to death and is only found the next morning. Another is 'Hansel and Gretel' where two children are abandoned in the forest by their parents and then face the threat of being eaten by a witch.
One book that might be similar is 'The Secret Keeper' by Kate Morton. It has elements of mystery and secrets within families, much like what 'the deepest secret novel' might imply.
