Volume Ninety Seven

From Tardis Wiki, the free Doctor Who reference

Volume Ninety Seven was one of Iris Wildthyme's diaries. It was bound in leather, and it had heavy, creamy pages, and the writing was done in watery blue ink.

The diary contained all of her experiences on Hyspero, so it was invaluable when she needed to find out why Anthony Marvelle wanted to get to Hyspero. (PROSE: Enter Wildthyme)
