Lives of Four Kings
The Lives of Four Kings is a book written by Grand Maester Kaeth about the lives of four Targaryen kings; Daeron I, Baelor I, Aegon IV and Daeron II. It barely mentions the reign of Viserys II Targaryen, who ruled after Baelor and before Aegon.
In his book, Kaeth argues that King Daeron I made a mistake when he considered marrying one of his own sisters to the Sealord of Braavos. Daeron planned to do this in order to make an alliance between the Seven Kingdoms and Braavos, aiming to remove the pirates from the Stepstones that were hindering the trade with the newly conquered Dorne. Braavos, however, was at war with Lys and Pentos, who lend the Dornish aid because of Daeron's plans.
There were only four copies remaining written in Kaeth's hand.

Tyrion Lannister gives a copy of Kaeth's work to King Joffrey I Baratheon as a wedding gift in 300 AC. The book is huge, bound in leather and gorgeously illuminated. Shortly after receiving the gift Joffrey carves the book up with his sword, Widow's Wail, which leaves only three copies remaining.
