The Darksmith Legacy

The Darksmith Legacy was a ten-book series featuring the Tenth Doctor. It was published by BBC Children's Books and supported by an interactive website.

Background
This ten-book series followed the Doctor on his exciting journey to discover the origins of the so-called Eternity Crystal and the powerful artisans who created it - the Darksmiths. The books had interactive elements. Readers had the option to go to the tie-in website to add points to a tally of points, so as to access additional content.

Books

 * Apart from the fiction, the books had TARDIS Data Banks containing more information and activity pages designed to tie in with the website.
 * Additionally, the books had cut-out or downloadable coupons entitling readers to an invitation to a party in London, provided they had completed the challenges.
 * The first 500 entries providing proof of purchase of any two titles in the series also could receive an exclusive slipcase for the ten-book series.
 * Each book ended in a cliffhanger leading on to the opening paragraphs of the next instalment of the ongoing storyline. With the exception of the first book, the first chapter of each book began with a reprise of the cliffhanger, like the television series.
