I can't resist a Buffy novel! And one focusing on Willow and Spike - not your usual combination of heroes, but it kind of worked.
I absolutely loved the premise of the story. It focuses on the history of the theatre - that the first 'plays' were actually rituals used to summon Gods and spirits. Although over the years the power has been diluted, using the correct incantation can do the same thing. Willow discovers this while taking a drama class at Uni, where she comes under the influence of a professor - one that Spike knew a long, long time ago.
Sadly, I don't think the author's did the concept justice. The chapters set in Ye Olde London, when Spike was still human, were completely distracting and a waste of time. Buffy fans will know his back story and new readers don't really need to know it in quite so detailed a way, as it only really impacts on the modern day situation towards the end ... and I guessing that most readers would have guessed who the professor is long before the big reveal!
The chapters set in the modern era were full of fun and adventure, just like a TV episode. It was good to see Willow get her own story, and it sort of fitted in with the series it's set against. I loved the fact that she was so angry about getting a fake 'A' when she wanted a fake 'A+' - so Willow!
But the ending, for me, was mangled. The big showdown happened in half a chapter and even though I read it twice, I'm not sure that I got it. Something seemed to have been missed out or maybe it was just so anti-climatic. I mean, I don't even know what happened to the professor - I guess our heroes won, but I'm not sure who! I can't help thinking that if the authors had dropped some of Spike's back story, there would have been more room for a more satisfying ending.
That said, it was still an enjoyable read and any visit to the Buffyverse is worth doing.
