Theres that strong sibling bond, and there's taking things too far.
This one takes it too far, but honestly glad it did.
It gives us the vampire story we are all after, but throws in the strongest bond there is, twins.
There's plenty of gore, and a wince inducing moment or two , and some great surprises along the way. I very much enjoyed both Sarah (all versions) and Lucy as characters.
Their fear of the asylum though, seemed over the top, in comparison to everything else happening in the story.
Overall, I was very entertained by this read.
