From the back of the book
Guided by Xelloss, an agent of the Greater Beast Zelas Metalium, Lina Inverse and her crew make their way to the heart of Dilse Kingdom--a country with many hidden mysteries--including the Claire Bible. While it seems fate has deemed that Xelloss take Lina to those manuscripts, she's not sure what his real plan is, but she really wants that Claire Bible, so she'll do whatever it takes!

Originally, Tokyopop had canceled the release of all the novels after the sixth book due to poor sales. They attempted to pass off volume six as the last book in the series, though there are actually 15 novels total (not counting the Slayers Special and Slayers Delicious novels).
Eventually, Tokyopop changed their minds and agreed to publish volumes seven and eight in English, thus completing the first novel story arc. At first, they planned to release them on a print-on-demand basis exclusively through the Tokyopop website, with the original release date being July 1, 2007. However, they eventually decided to release them in bookstores instead, and moved the release date to January 2008.
At the present time TOKYOPOP has no plans to release the remaining Slayers novels (volumes 9-15, which make up the second novel story arc).
