Nothing in Owen's life has been right since his father died in prison, accused of a crime Owen is certain he didn't commit. Monroe, the IT guy at school, might finally bring Owen the means to clear his father's name by letting him use an Animus-a device that lets users explore genetic memories buried within their own DNA. During a simulation, Owen comes uncovers the existence of a powerful relic long considered a legend-the Trident of Eden. Now two secret organizations will stop at nothing to take possession of this artifact-the Brotherhood of Assassins and the Templar Order. It becomes clear the only way to save himself is to find the Trident first. --Publisher.

Owen and his fellow teens travel to Denmark, the site of an ancient Viking battle, to search for the last key to the Trident of Eden and uncover the truth behind their collective unconsciousness.

In Last Descendants Book One, Owen and a group of other teens located the first piece of an ancient and powerful relic long considered a legend--the Trident of Eden. This piece was sought by the Brotherhood of Assassins and the Templar Order, but before either organization could take the piece, it was stolen by an unknown, third party. The tenuous relationship between Owen and the teens fractured, with some taking sides with the Templars, and others with the Assassins. Book Two picks up weeks after the events of book 1. There are still two pieces of the Trident of Eden to find, and both groups are determined to not repeat their mistakes. The next piece is said to have been buried with Mongol Warlord Genghis Khan, whose tomb has never been found. Now the teens on either side of the conflict will have to go deep into simulations in war-torn Mongolian China in a race against time to discover the next piece--and ensure their safety--before the others.
