I don't know who the author of the 'Sands of Time Novel' is. There are so many novels out there, and this title isn't very common knowledge without more context.
The 'Sands of Time Novel' could be about a journey. The sands of time here might symbolize the finite nature of life or a specific period in which the story takes place. It could involve characters on a quest, either physical or spiritual, and as they move forward, the sands of time keep flowing, representing the unstoppable progression of events in their lives.
The 'Black Sands Story' could be about many things. It might be a story related to black sands, perhaps a tale set in a place with black sand beaches. It could involve adventures, like a character exploring the area with black sands, or it could be a story about the origin or significance of those black sands.
The secrets could be about the unique culture. For example, the traditional Bedouin way of life that has been preserved in some parts of the Emirates. Their skills in desert survival like finding water sources and navigating the vast sand dunes are also part of the secrets.
Bobby Sands was an Irish republican. He was part of the hunger strike in the Maze Prison. Sands was protesting against the British government's policy of criminalizing IRA prisoners. His sacrifice brought international attention to the situation in Northern Ireland and became a symbol of the struggle for Irish independence.
