The shape of things to come

It's a new start for Zoe, the unexpected girl who still has a lot to learn about who she is, what she wants and who she wants. Luckily, she's traveling with the last Time Lord she has left. Takes place after season 3. Timey-wimey. You don't have to read it if you haven't but it's a sequel to "the unexpected girl". (Rated T but chapters 15 to 22 should probably be rated M)
