In 1760, astronomer Guillaume le Gentil sets out on a quest through the oceans of India to document the transit of Venus. The weather is turbulent, the seas are rough, but his determination will conquer all. In 2012, divorced estate agent Xavier Lemercier discovers Guillaume’s telescope in one of his properties. While looking out across the city, the telescope falls upon the window of an intriguing woman with what appears to be a zebra in her apartment. Then the woman walks through the doors of Xavier’s office a few days later, and his life changes for evermore . . . Part swashbuckling adventure on the high seas and part modern-day love story set in the heart of Paris, An Astronomer in Love is a time-travelling tale of adventure, destiny and the power of love.
