Sojourn (Time Rovers, #1)

London, September 1888. An aged Queen Victoria rules. The threat of anarchy hovers in the air. A new kind of evil lurks in the back alleys of Whitechapel. Enter Jacynda Lassiter, a Time Rover on a mission find an overdue tourist' and return him to 2057 before he changes history.
Victorian London is a dangerous place for the unwary. Mysterious shape-shifters haunt the streets, making friend and foe indistinguishable. When a fellow Time Rover is murdered, Jacynda's mission becomes personal. Can she trust the two gentlemen who come to her aid, or do they harbor their own dark secrets?
In a few days, Jack the Ripper will add to his bloody legacy. But old Jack isn't the only threat in Whitechapel. Unless Jacynda can outwit a madman, her Victorian sojourn will rewrite history and end at the point of a blade.
