I have to admit that this was one of the slower starting Doctor Who novels I’ve read, but it was worth it for the final payoff. Jaime and Zoe are separated on a near-future Earth that has been attacked by aliens for no apparent reason. The Second Doctor was killed in front of them, but the Earth forces believed he was one of the aliens and they did some experimental treatments that prevented his regeneration, making them believe the Doctor is one of the aliens’ Indestructible Men of the title.
What’s really cool about this novel is that it’s a glowing homage to the Gerry Anderson shows of yesteryear. Elements of Fireball XL-5, UFO, Thunderbirds, Space 1999, and especially Captain Scarlet and the Mysterons are woven together, with what seemed to me to be a dash of The Quatermass Conclusion. And yet, like most of the Past Doctor adventures, the story wasn’t aimed at kids, which was a pleasant surprise.
Very well-written, this was a very enjoyable read and I think any fan of British science fiction, or weird puppet sci-fi, will enjoy it.
