Books Given its content, a very short story within an anthology threaded through a fact based look at the television series approach to science, Natural Regression is a nonetheless fairly momentous entry within the franchise. The first new piece of Eighth Doctor prose published by the BBC Books imprint since Fear Itself in 2005 (Spore was a Puffin eBook), it's also the opening salvo in a coincidental multi-platform reveal of what happened him between the end of the Big Finish audios and his regeneration (including a comic series and audio) refreshing the character again. As one of the architects who helped establish the character, despite the slender pagination, Justin Richards instantly captures Eighth in his usual status quo, planets and galaxies exploding all around and just him and his small blue box trying to do their best against insurmountable odds. The motivation for this small adventure fits within the scientific theme of the book (as well as poignantly paying homage to the educational roots of the series) and the only criticism I have is that it ends at just the moment when you want to read about him going off on further adventures with a potential new companion. After nearly twenty years, this version of the character continues to surprise.
