Ruby is 16 and lives at Camp Thurmond, a government-run work camp with harsh restrictions and brutal punishments in The Darkest Minds, by Alexandra Bracken. She has been there since she was 10, shortly after a deadly virus appeared and proved fatal to most of Ruby’s classmates. Survivors of the virus developed psychic abilities of varying levels, and they were grouped into five classifications that indicate their power/danger level: Blue, Green, Yellow, Orange, and Red, with red being the most dangerous. Ruby is secretly an Orange who has tricked the officials (her power is entering other people’s minds) into believing she is a Green, which has kept her safe until now. But the officials are aware that there are some hiding Yellows, Oranges, and Reds, and they are using new tactics to ferret them out.
