Although Orange Is the New Black is loosely based on Piper Kerman's memoir about her 13 months behind bars, people don't expect it to be completely loyal to the book now that it's entering its sixth season.
After all, we've had murders, break outs, and prison riots since the modest first season aired, and many real inmates have criticized the show for being an inaccurate depiction of the prison experience.
However, Piper really did serve 13 months behind bars, and met a colorful assortment of women who would inspire the characters on the show during her time there. But, of course, since this is a Netflix TV show, and every episode must be binge-able, the characters became very different from their real-world counterparts.
Here's a look at each OITNB character and how they differ from their depiction in the book. (Warning: spoilers!)
