Two new Doctor Who crossover novels, Legends of Camelot and The Wonderful Doctor of Oz, will be available on 10 June.

Both Puffin Classic novels are written by Jacqueline Rayner.

Legends of Camelot

“While investigating a strange energy in Carbury, the Tenth Doctor and Donna Noble are pulled into a different dimension, smashing a giant hole into another world in the process.

As the magic of the hidden dimension slowly seeps out, the Doctor and Donna find themselves in Camelot, where a young squire, Arthur, comes to their aid, and when the Doctor is mistaken for Merlin, they are swept up in the glamorous and daring legends of the Knights of the Round Table.

But something far more menacing has been awakened. Caught in an ancient battle for power, Donna and the Doctor are sucked into a dangerous game. As each move is made and time spins faster, the Doctor must find a way to seal the rift before an unimaginable power is unleashed and the universe is laid to waste.”

The Wonderful Doctor of Oz

“When a sudden tornado engulfs the TARDIS, the Thirteenth Doctor and her fam find themselves transported to the magical land of Oz. With a damaged TARDIS and an unexpected stowaway from the 1930s, their only hope of getting home is to follow the yellow brick road.

But when an army of scarecrows ambushes them, they quickly realise that everything is not as it should be, and they’re thrown into a fight for survival against a mysterious enemy. As each of her companions becomes a shadow of their former selves, only the Doctor is left standing.

Desperate to save her friends, she must embark on a perilous journey to seek help from the mysterious Wizard of Oz – and stop whatever forces are at work before she and her friends are trapped in the fictional world forever.”

Both books, Legends of Camelot and The Wonderful Doctor of Oz are available for pre-order ahead of their release on 10 June.
