Translation of: Les Caprices d'un astre,

In 1760, Guillaume le Gentil sets out on a quest through the oceans of India, to document the transit of Venus at the request of the King. The weather is turbulent, the seas are rough, but Guillaume's determination will conquer all. In 2012, divorced estate agent Xavier Lemercier finds Guillaume's telescope by chance in a cupboard in one of his old apartments. While looking out across the city, the telescope falls on the window of a beautiful brunette woman. Xavier watches her wistfully from afar, until the day she walks through the door of his office, and his life changes forever. From the best-selling author Antoine Laurain, An Astronomer in Love is a time-travelling epic-in-miniature of adventure, destiny, and the power of love.
