THE MERCER LOCK

Adrian Mercer has spent twelve years travelling into the past for the British government, preventing disasters before they happen.

His official record lists seventeen missions. His medical records reveal twenty-six.

Someone has erased nine journeys.

After a woman at St Pancras Station recognises him from an encounter he cannot remember, Adrian begins investigating the gaps. Fragments of his missing past cast doubt on the Meridian Directorate, the organisation he has trusted to decide which events should be changed.

With Meridian preparing an intervention that could secure its power, Adrian must recover the truth about his own work—and decide what to do with it.

But undoing the Directorate’s actions could also undo lives he helped save.

A science-fiction conspiracy thriller about stolen memories, compromised loyalties and the danger of giving anyone the power to decide which history survives.
