Every working mum has had to face it. The guilt-fuelled, anxiety-filled first day back in the office after maternity leave. But this working mum is one of a kind.

Meet Alexis Tyler. An elite covert agent within Her Majesty's Secret Service.

Her first project back is a high-stakes hit of global significance and the old boys network of government espionage is far from ready for the return of an operational mother. But woe betide anyone who ever tells Alexis Tyler 'you can't'.

She will have it all. Or she'll die trying... And yes, she damn well will be home for bath time.
