Everything else Rehoboam did while he was king, including a history of his family, is written in the records of the two prophets, Shemaiah and Iddo. During Rehoboam's rule, he and King Jeroboam of Israel were constantly at war.
The History of the Kings also tells more about the sons of Joash, what the prophets said about him, and how he repaired the temple. Amaziah son of Joash became king after his father's death.
Everything else Solomon did while he was king is written in the records of Nathan the prophet, Ahijah the prophet from Shiloh, and Iddo the prophet who wrote about Jeroboam son of Nebat.
