"One of Our Thursdays Is Missing" is the sixth novel in the Thursday Next series by Jasper Fforde, and unlike many series, it is absolutely essential for the reader to have read the previous five volumes if one hopes to have a glimmer of a clue as to what is going on. That said, anybody who loves literary fiction, absurdism along the lines of Flann O'Brien and jaw-droppingly funny puns, allusions and other forms of written humour will, I hope, have already discovered the mad genius that is Mr. Fforde's written world. It's not really possible to describe what this book is about, other than to say it takes place mostly in BookWorld, the island world located inside a sphere in which all of the characters of written works live and from which they act out their lines whenever someone in the real world is reading their book. BookWorld is only one of many such realms, but we are concerned primarily with Fiction Island and its islets, where a Genre War of epic proportions is about to break out, and only Thursday Next can stop it. But the real Thursday is missing, so it falls to her fictional counterpart to do her best, even knowing that her best is nowhere near good enough....Jasper Fforde is easily one of my top 3 or 4 authors, and while I will never again have the joy of experiencing his fiction for the very first time, every single new volume from him is a cause for celebration. I cannot recommend this series highly enough, but I do caution that you must read the whole series, starting with "The Eyre Affair" and proceeding in order of publication. If you love good writing and inspired creative lunacy, you will be very glad to discover Jasper Fforde.
