One way to rewrite it is as a 'double secret author discovery story'. The author is on a path of discovery. The two secrets could be related to a new scientific finding or a historical discovery. For example, the first secret could be about a lost civilization's language and the second could be about an ancient technology that was thought to be lost. The author's journey of uncovering these secrets can be full of excitement and learning.
It could be rewritten as a 'double secret author growth story'. The author experiences two important events that are initially secrets but later become catalysts for their personal growth.
