The Great Big Book Exchange - sometimes referred to as the Exchange - was a large bookshop located on South Road in Darlington. The Exchange was owned by an alien named Terrance who was familiar with every book in the store. Kelly worked at the cash register.
In 2011, Terrance was killed in the crash of the Begins at Home, leaving the Exchange to be inherited by Simon. However, Simon was prevented from taking over the business because he began travelling with Iris Wildthyme. While Simon was gone, Anthony Marvelle broke into the exchange and stole the Aja'ib and the Objet D'Oom. Simon eventually returned to the Exchange with Iris and Panda and they discovered what Marvelle had done. Iris was able to deduce that Marvelle was intending to use the stolen items to open the Ringpull. (PROSE: Enter Wildthyme)
Behind the scenes Edit
Enter Wildthyme was the third Paul Magrs novel that the Great Big Book Exchange appeared in. The Exchange originates from the 2006 novel Exchange, which also introduces Simon, Kelly, and Terrance. In one scene in the 2010 novel The Diary of a Dr Who Addict, the main character David visits the Exchange during a trip to Darlington.
