City of Shadows A Trap in Time and The Host Rides Out (Silver Silver Trilogy)

Book 1: Twelve-year-old Davey discovers the exceptional power of his sixth sense when he explores the ancient underground city in his hometown. Here he confronts both good and bad spirits and one evil shapeshifter who follows him back to his own time to bring him to his death. Book 2: From the author of Witch Child. Davey's grandmother has always told him he has the gift of second sight. But it never seemed real, just a stupid old wives' tale. Until now, the darkest time of the year...Davey encounters a strangely familiar face and finds himself locked in a terrifying trap in time when past and present collide. Age 11+. Book 3: Paranormal activity is creating chaos for all who live and work in the city, and Davey is more alert than his sister and cousins to voices from the past. Will the ghost hunter brought in to investigate uncover the root of the problem, or is his very presence a trigger for evil sprits to make themselves known? And now Davey must be on his guard as never before-his nemesis, The Lady, has returned; he must escape her deadly clutches by Midsummer or be in her thrall forever.
