Book of days

Young Cameron Vaux's mind is slipping. Memories of his wife, killed two years earlier in a car accident, are vanishing just as his dad predicted they would. His father tells Cameron that to save his mind he must find 'the book,' the past and future record of every soul on earth. When an obscure clue leads Cameron to a small central Oregon town, he meets enigmatic Taylor Stone, a possible guide to finding the book which seems to carry secrets far deeper than anyone imagines.
