Leaping

"Jack and Francis work in a call-centre in Manchester, where they are endlessly tormented by irate customers and sinister bosses. When Jack's girlfriend Jennifer buys Fell House, a mysterious ruin out in the remote mountains, a move to the country seems like the answer to all their problems. But an ancient evil is waiting in the valleys - Fell House has another owner."
"An edgy, original and terrifying werewolf novel, the first in a series from a young debut author exploring the darkness that lies beneath Britain's bleak post-industrial northwest. Jack finished university three years ago, but he's still stuck in a dead-end job in a sinister call-centre in Manchester. When the beautiful (and rich) Jennifer comes into his life he thinks he has finally found his ticket out of there. Trouble is that his boss is interested in Jennifer as well, and there's something strangely bestial about him. So when Jennifer buys Fell House, a mysterious old farm out in remote Cumbria, a house party on a legendary scale seems like the perfect escape. But as the party spins out of control on a seemingly neverending night, they must face up to the terrifying possibility that not all their guests may be human'and some of them want to feed. An astonishing and innovative blend of horror, folktale and disturbing realism, The Leaping is the first installment in what is shaping up to be a genre-defining series."@en
