The Curse of the Vampire Robot by Graeme Base

"Deep in the Scottish Highlands,
Many years from now..."
 
Gertie Gif, a lowly cleaning droid from the village of Loch Lan, sets out on an heroic quest to liberate her fellow robo-folk from the curse of a legendary, battery-draining laptop who lives in the castle on the hill.
Will Gertie and her little software-wolf companion succeed in cleaning out the vampire's corrupted heart?
Or will the Curse of Voltoid remain forever hanging over the valley?
Classic vampire mythology meets nerdy computer-speak in a rhyming tale of adventure, bravery and compassion from master storyteller Graeme Base.
