The Divergent Series Four-Book Collection Box Set by Veronica Roth is a collection of all four books in the Divergent trilogy, plus a companion novella told from the perspective of the character Tobias Eaton. The four books in the series are:

• Divergent (2011)
• Insurgent (2012)
• Allegiant (2013)
• Four: A Divergent Collection (2014)

The Divergent trilogy is a dystopian science fiction series set in a Chicago-like city that is divided into five factions: Abnegation (the selfless), Amity (the peaceful), Candor (the truthful), Dauntless (the brave), and Erudite (the intelligent). The story follows Beatrice Tris Prior, a young woman who discovers that she is Divergent, meaning she does not fit neatly into any one faction. When she chooses Dauntless during the Choosing Ceremony, she must undergo a grueling initiation in order to stay with the faction.

The companion novella, Four, is told from the perspective of Tobias Eaton, also known as Four. The novella explores Four's past and his motivations, and it provides new insights into the events of the Divergent trilogy.

The Divergent Series Four-Book Collection Box Set is a great way to experience the entire Divergent saga. The books are fast-paced and exciting, and they will keep you guessing until the very end. If you are a fan of young adult dystopian fiction, then you will love this series.
