Suffice to say, I'm a big fan of the saga. However, I had a harder time holding onto this volume, far from our favorite heroes. This tome longer had a place in spin-off as "Witches of épouvanteur" rather than eleventh book in the series, while I loved the Volume 9 dedicated to Grimalkin which although also leaving the Usually, even when allowed to pursue a part of history. Moreover, the attractiveness of Volume 11 regarding the history of the saga is the appearance of the latter, but I think it comes too late in the book (about 200th on page 300). This criticism is in no way a criticism of the writing of Joseph Delaney is still good.
