Kate Moore is a working mother, struggling to make ends meet, to raise children, to keep a spark in her marriage...and to maintain an increasingly unbearable life-defining secret. So when her husband is offered a lucrative job in Luxembourg, she jumps at the chance to start anew. While Katie reinvents herself as an expat, her husband works incessantly at a job she has never understood. Then another American couple arrives, and Kate becomes suspicious that these people are not who they claim to be, and begins to peel back layers of deception.
