Darkseed: Awakening (Darkseed, #1)
205 Cheyne Avenue holds some dark secrets...After an accident claims the lives of two boys, fifteen year old Sarah Walton moves in to 205 with her mother. It isn't long before she realises there is another, unseen resident, and convinces best friend Christina to help her make contact. When they do, the girls learn more than they bargained for, and soon find themselves desperately unravelling a series of clues in order to stop a malevolent being, seemingly bent on manipulating the souls of those he's killed in order to gain omnipotence. Their only ally is Craig, a spirit they've befriended via a Ouija board, but as the story unfolds, the girls discover things aren't quite as straightforward as they'd assumed.
