Up until now, to get a general idea of the Second Age, readers of Tolkien have had to rely on various, mostly unfinished, accounts. In this History of Númenor and Middle-earth of the Second Age, two Tolkien experts -researcher and translator Martin Simonson and novelist and YouTuber Bernard Torelló (also known as Kai47)- join forces to explain the entire Age in a single work.

Through an evocative and detailed chronicle spanning more than three thousand years, from the founding of Númenor and the Grey Havens to the defeat of Sauron in the War of the Last Alliance, this History collects and comments on everything Tolkien had to say about Númenor and Middle-earth in this fascinating era. The book contains more than sixty illustrations (the vast majority in color) with Second Age motifs by internationally renowned artists, including Anke Eissmann and Christopher Rådlund.

In addition, there are six detailed color maps; a large number of informative tables on the most varied curiosities of the Age; complete chronologies and an original dictionary containing all the terms relating to the Númenórean culture. .
