It depends on the plot and writing style. Some novels might do a great job of keeping secrets as part of the story, while others might not focus on that aspect too much.
In 'The Secrets We Keep Based on a True Story', one of the main secrets appears to be a past encounter or relationship that has some dark aspects to it. It could be a situation where a character did something wrong during a war or a difficult time. Another possible secret might be related to the identity of someone in the story, perhaps a hidden family connection or a false identity that was created to hide from the past. The movie seems to be about how these secrets shape the characters' lives and how they struggle to keep them hidden while also dealing with the consequences of their actions in the past.
The novel 'Secrets You Keep' probably delves into the complex web of secrets that the characters hold. It could explore how these secrets shape their lives, decisions, and interactions. Maybe it has a mystery element where the discovery of one secret leads to a cascade of revelations, ultimately changing the characters' fates.
I'm not sure exactly who the main characters are without reading the novel, but they could be an ordinary person with a big secret, and perhaps a friend or family member who is affected by that secret.
To keep your novel organized, try breaking it down into sections or chapters. Have a consistent timeline and make sure events build logically. Also, keep track of subplots and how they relate to the main story.
