Time and Relative Dimensions

Gabby was a normal girl. Lonely, but normal. Until one day, she finds an old box in the woods. To save the Doctor, she has to become part of the TARDIS, knowing everything that ever was and ever will be. The price is great, but the adventures ensue.

Ryan had lost his sense of adventure, his imagination. That all changes when he meets Gabby, and learns that the wonderful adventurous stories she tells him are all true. He wants to become part of that life. He finally gets the chance, but will he regret it?
