The Crimson Blade (en Inglés) - Ken Peter Kirk

Scotland, 1622. When a mysterious girl arrives at the house of The Laird Grant, she brings with her a secret that has spanned more than eight hundred years and a gift that will change one young life forever.Wild Flower has walked through time itself, crossing centuries in a single stride at the middle of a meadow. She can close her eyes and see what others cannot: The past, the future and the hidden truths that people carry in their hearts.
As companion to the Laird's sharp-tongued granddaughter Logan, she has found something she never expected. A friend worth dying for.
Wild Flower has not come merely to offer friendship. She carries a revelation that will shake Logan to her core. In a land where darkness gathers and ancient vampires reach out from the shadows to threaten queens and kingdoms alike, a legendary figure is destined to rise. They are a slayer so swift and so deadly that the creatures of darkness will learn to fear a single name.
She is: The Crimson Blade.
As clan tensions simmer and treachery festers in the Scottish Highlands, Logan must confront a destiny she could never have imagined. The girl with servants who clears away her own dinner plates and who laughs until she cries must somehow become the warrior of prophecy, a vampire slayer whose silver daggers can cut the buttons from a man's shirt or pierce his heart with equal ease.
Destiny demands a price. Between the ten-year-old girl who hates her own nightmares and the fearless swordswoman she is fated to become, lies a journey through danger, loss, and the strange, wild magic of 'The Quickening'. With enemies closing in and the fate of a kingdom hanging in the balance, Logan will discover that the most extraordinary power of all is the bond between two girls whom time itself could not keep apart.
The Crimson Blade is the second book in The Burning Tree series. It is a tale of friendship, destiny, and the making of a legend.
