H'Kig Book of Laws
From Wookieepedia, the Star Wars wiki.
The H'Kig Book of Laws was a publication purporting to deal with the laws of the reclusive H'Kig religious order. While visiting seedy Atzerri to discover the whereabouts of his mother during the Black Fleet Crisis in 16 ABY, Luke Skywalker came across a satellite store of the Galactic Archives at the Traders Plaza which promoted the book in one of its adverts. However, the Jedi dismissed the book along with the others advertised including Palpatine's Principles of Power and The Lost Secrets of the Jedi as frauds.
