Northern Spy by Flynn Berry

A single mom of an infant balancing little sleep, hormones and a job with the BBC is stunned when she sees her sister on a security camera in a robbery and working with the IRA. Tessa and Marion are close and Tessa cannot believe that her sister would be a part of this but she will not turn her sister in.
Soon Tessa is pulled into a very dangerous game of helping Marion pass information to MI5. If either of them is caught there will be no second chance or time to say goodbye to Finn. This tight political thriller shows us both the violent and very human side of these activists. This tie to motherhood and family loyalty shows us a very different side to what you see on the news. 4 stars
