I enjoyed this book. It was a fun, quick read with a new take on the Arthurian legends. I enjoyed the characters quite a lot. Bizzy, in particular, was a driving force that kept me interested and involved. Lizzy was a well written teenage character trying to deal with outrageous circumstances, as was depicted realistically. The author didn't turn Lizzy into an instant bad-ass as soon as she received her gift. There was a natural progression to Lizzy and the setback to her quest.
I especially liked the tie-in's to Arthurian legend. Vivienne was a wonderfully wicked character and the Seven Sisters were used wisely to move the story without overpowering Lizzy and Bizzy.
