According to the Oxford English Dictionary:
Vacillate • verb 1 waver between different opinions or actions. 2 be indecisive: I vacillated between teaching and journalism. Origin: late 16th century (in the sense ‘sway unsteadily’): from Latin vacillat- 'swayed', from the verb vacillare.
Vacillation • noun 1 the inability to decide between different opinions or actions. 2 indecision: the First Minister's vacillation over the affair. 3 state of being unable to do something.
And its obvious from looking at GoodReads that vacillating is what the publishers of Deanna Raybourn's masterful (YUP, that's the word I want to use :) Lady Julia Grey series are currently doing.
Now, I know publishers from different countries decide on different covers. (Yes, UK and USA I'm looking at you!) I know that sometimes publishers decide that the adult version of a book should have a different cover from the non-adult version. (Yes, Bloomsbury I'm looking at you and thinking of the Harry Potter covers. Do you know how many time I had to explain while placing my pre-order for the next Harry Potter book that no, I didn't want the ugly adult cover, and yes, I knew that I was an adult but I still wanted the bright, non-adult cover.) Can't you just pick a cover and stick with it? Especially in this day and age when a reader can sit at their computer and order a book from the other side of the world! Do we need all this variety? I mean the covers for the first two books are just so different! I really, really, really want to buy this series, but until I have a definitive idea of what style of cover the publishers are going with I'm not parting with a penny. And I know I say that it's size that matters, but...if I'm going to buy all of a series in one go I would like to have the covers match. That doesn't seem too much to ask, does it?
So, where do you sit on the covers fence? Do covers need to match?
