Clearly, the hero of time has not failed today.
The Legend of Zelda: Hyrule Historia, the book compiled by Nintendo for the 25th anniversary of the Legend of Zelda franchise last year, is currently on sale at Amazon for $17.49, half of its usual price of $34.99.
The book is most notable for the official timeline of the series, which takes a controversial approach to fitting everything together. It also includes a lot of various artwork and material related to the different games in the Zelda franchise.
