"The translated version of the 'Secret Russian KGB Book of Alien Species,' stirred controversy among the researchers. This mysterious KGB book turned up when a deceased Ukrainian officer’s son found it among his belongings. This text revealed the alien races that had contacted Earth.
'The Book of Alien Races' was translated from Russian into English by Dante Santori, a former special forces sergeant from Europe. The original 1946 book was written to inform KGB agents of the various alien races who had visited Earth and also was used as a notebook by secret agents as they constantly made additions and revisions to the original startling information over the years."
