I also read Marc Aronsen’s Master of Deceit, a teen biography of J. Edgar Hoover. Aronsen is a master of narrative fiction, and I thought the way he tried to show two sides to every story was great. For interested teens, this could be a really good discussion book. I did catch some bias on his part, which he addresses more explicitly in the afterword. I didn’t actually know much about J. Edgar Hoover before reading this, but I now I feel quite well informed.
