The Prideful Mr Darcy and The Present-Time Lady

Kate Bennet is a normal 19-year-old English Lit. student at the Hertfordshire University until she wakes up one day suddenly much younger and in 1801. She has not simply ended up 200 years in the past though, she has become one of the characters of 'Pride and Prejudice',10 yrs before the story begins. How her presence will be able to change the story as we all know it? Darcy/OC.
