(Series 7, Book 2)

A new reality has been created by the temporal disruption ripping through
the causal nexus. Welcome to 1978… with a difference.

Anne Travers, co-founder of UNIT, and her husband, Bill, are celebrating
their wedding anniversary in France, which is the perfect opportunity for
Anne to catch-up with an old friend; Madeleine Bonnaire.

At the institute owned by Madeleine’s father, one professor is more
interested in his own project than any work for which Bonnaire has hired
him. His need for secrecy and his attitude irritates his assistant, Paul
Larousse, who would prefer to dwell on his feelings for Madeleine.

Meanwhile, Victor Bonnaire is not at all happy to hear of Anne’s visit, not
least of all because he’s always viewed Anne as a bad influence on his
daughter.

What seems like a simple case of familial friction takes a bleak turn when
a local unknown threat makes the news. Suspicion abounds and throws
Anne and Bill into an unexpected mystery. What is the strange threat,
and does it present a direct danger to anybody at the institute? Or to
those who ask too many questions? Unable to walk away from her friend,

Anne has no option but to investigate, little knowing she’s about to face
the darkest shadow of her life so far.
