A timeline is just an illusion because time doesn't always run in a straight line. In a moment of monumental change time can fracture and jump. When that happens nothing is ever predictable, or stable, again.

Sarelle is a normal nine year old girl in 1910. Until one night her world plunges into the unknown and she becomes an involuntary time traveller.

She has no control over where she goes or when she leaves.

If she has the ability to jump through time, then how will her encounters with the Cullens effect their lives?
