She has law degrees from Norway, France, and the United States, and is a member of the New York Bar. She worked numerous years in law and finance in Paris, France, and Geneva, Switzerland.

Unni is the author of the award-winning The Mystery of the Lone Wolf Killer, published by Pegasus Books (New York, 2015), which examines Norwegian mass murderer Anders Behring Breivik from both a psychological and sociological perspective, and focuses on what we can learn from that tragedy to prevent additional rampage killings in Norway, the United States, and the rest of the world. While researching mass killers, he learned a lot about rage and loneliness. She is also the author of the forthcoming Betraying the Nobel: The Secrets and Corruption in the Nobel Peace Prize, published by Pegasus Books on November 3, 2020, which focuses on the lack of leadership in the world and on the Nobel Peace Prize’s importance as a beacon of hope and inspiration.
