Both are books probably lost to time, though maybe one day one or all will be found. They are mentioned in 2 Chronicles 9:29

“Now the rest of the acts of Solomon, first and last, are they not written in the book of Nathan the prophet, and in the prophecy of Ahijah the Shilonite, and in the visions of Iddo the seer against Jeroboam the son of Nebat?”

It is also mentioned in 2 Chronicles 12:15 relating to Rehoboam and 2 Chronicles 13:22 relating to Abijah.
