Not the best Doctor Who MDA, but a valiant attempt to fill in a missing chapter. The writing is extremely clunky throughout but occasionally yields gems such as this:

"Our lives have so many advantages, Melanie. We see myriad things we'd otherwise be denied. But there's a price to pay. Your price is not knowing. Mine is knowing."

I mean, that's GREAT. 

Am I sorry I read this, No. But will I be reading it again? Also no.
