Curiouser and curiouser! This fun tale from the madcap mind of Paul Magrs thrusts the TARDIS travellers into the world of Alice’s Adventures in Wonderland.

Taking a break in Oxford, the Fifth Doctor and his companions run into Alice-author Lewis Carroll at a garden party. But when all their fellow guests turn into animals, they realise all is not as it seems… An unknown cosmic foe has trapped them in a twisted version of Wonderland. Separated from the TARDIS and from each other, their only hope of escape lies in cryptic clues teased by fan-favourite characters from Carroll’s classic tale.

This book is the latest in Puffin’s mash ups with other fictional realms, following on from titles such as Josephine and the Argonauts, Legends of Camelot and Rebellion on Treasure Island. In Wonderland is available from the usual stockists (RRP £9.99), but we have FIVE copies to give away to those who can answer this question:
