This Doctor Who novel is epic in scope from contemporary Mexico to the Aztec empire to hippie London in the 60s to the John Lennon assassination to the sinking of Titanic. And yet, this may be the most internal story for the Doctor and his companions. Their relationship is strained, especially the Doctor and Ace since she's become something of soldier during her absence from the TARDIS. Worse yet, the Doctor faces an antagonist manifest as an Aztec god who is altering history. The Doctor's usual strategy of manipulating people and events fail and we see him at his most defeated. This novel is good in that it's a rare story that's set in Latin America in both precolonial and contemporary settings. The only downside is that like Timewyrm: Exodus it credits some historical acts of human evil to extraterrestrial influence. This was the first novel by Kate Orman, who was also the first woman and first Australian to write for the Doctor Who line, and it's a pretty remarkable achievement in how it reimagines what a Doctor Who story can be.
Favorite Passages:

"Has it ever occurred to you that the reason the sacrifices are made is to dispose of foreign warriors taken captive in battle – and to cause more and more battles to be fought?’"

"‘It’s already written in the book of history,’ he continued. ‘Painted in the records. Nothing I can do or say is going to change it. But there’s something else here, something that isn’t in the book, or wasn’t the last time I visited. Things have changed. Something’s wrong. Someone’s interfering. I need to find a way to read between the lines…’"

"‘Time travel,’ said Bernice, ‘is like banging your head on a brick wall. Only someone keeps moving the bricks.’"

This New Adventure takes the Doctor, Ace and Benny back and forth in time to crucial points like the murder of John Lennon and the sinking of the Titanic, on a trail originating in Mexico in the fifteenth and also twentieth centuries. There are consciousness-altering drugs and prose which reminded me of Ian McDonald, and a satisfying resolution to the pursuit of a mostly non-corporeal baddie. ( )
