One of Our Thursdays is Missing

This book is not intended to be read as a standalone, as it relies heavily on established lore and the complex internal mechanics of the BookWorld that are developed throughout the preceding series entries.

While previous books focus on the real-world Thursday Next, this installment shifts the perspective to the written version of Thursday, a fictional character who exists within the books that the real Thursday inhabits.

The title is a deliberate reference to the 1942 British war film One of Our Aircraft Is Missing.
