SEASON OF THE WITCH by NATASHA MOSTER (cover may differ)

TWO SISTERS. A MYSTERIOUS HOUSE. ENTER A WORLD OF BEAUTY AND DARKNESS….

Gabriel Blackstone is a cool, hip, thoroughly twenty-first-century Londoner with an unusual talent.  A computer hacker by trade, he is - by inclination - a remote viewer; someone whose unique gifts enable him to 'slam rides' through the thought processors of others. 

But reading people's minds is something he does with the greatest reluctance - until he is contacted by an ex-lover who begs him to use his gift to find her stepson, last seen months earlier in the company of two sisters.

And so Gabriel visits Monk House in Chesea, a place where time seems to stand still.  The living room is filled with the perfume of roses, African masks line the walls and everywhere - on doors, on walls, on ceilings even - the mysterious coded symbol of cross and circle dominates. 

As the days of summer turn into a cold and hostile winter, Gabriel becomes increasingly bewitched by the house, and by its owners, the beautiful, enigmatic Monk sisters - one of whom is a killer, who will stop at nothing to protect a terrifying secret as old as time itself.
