In 1844, at 94 years of age, Caroline Herschel was in themidst of a frustrated attempt at writing her memoirs. She sent the writings and many letters to her niece Arabella, suggesting the girl 'twist it into a Novel entitled The Life and Adventures of Miss Caroline Herschel'. Arabella never wrote the proposed novel, but Caroline's story is brought to life in Double the Stars.
Escaping a life of drudgery with her mother, Caroline becomes a successful singer in high society 1780s Bath, but this life is wrenched from her when her brother, William, is appointed astronomer to King George III.
As William makes discoveries that shoot him to celebrity, Caroline falls in love with astronomy for herself, making her own discoveries about the skies she sweeps from the roof-top. Friendship, love, betrayal and loyalty compete in this beautifully rendered life of an extraordinary woman living in extraordinary times.
