The Captain and I (doctor who fanfic)

Alice Jessica Melinda Vines (18) was... strange. She was the orphan who preferred the streets and just dreamed of adventure. Knowing something is wrong at the local orphanage she begins to investigate. Then while doing some running she meets the handsome (and sexy) Captain Jack Harkness, who of course leads her to adventure (and flirting). She even meets the Doctor!
But before long, it becomes obvious that something is off about Alice, will Jack and Alice figure out what it is? Or will it be too late?
