Cover Blurb for The Ship Who Sang
From Amazon
The brain was perfect, the tiny, crippled body useless. So technology rescued the brain and put it in an environment that conditioned it to live in a different kind of body - a spaceship. Here the human mind, more subtle, infinitely more complex than any computer ever devised, could be linked to the massive and delicate strengths, the total recall, and the incredible speeds of space. But the brain behind the ship was entirely feminine - a complex, loving, strong, weak, gentle savage - a personality, all-woman, called Helva...
From Wiki
The Ship Who Sang (1969) is a science fiction novel by American writer Anne McCaffrey, a fix-up of five stories published 1961 to 1969. It is also the title of the 1961 novelette which is the first of these stories. The series started by the book, the "Brain & Brawn Ship series", is sometimes called the "Ship Who Sang series".
The protagonist of the 1969 novel and all the early stories is a cyborg, Helva, a human being and a spaceship, or "brainship". The five older stories are revised under their original titles as the first five chapters of the book and the sixth chapter is entirely new.
McCaffrey dedicated the book "to the memory of the Colonel, my father, George Herbert McCaffrey, citizen soldier patriot for whom the first ship sang". In 1994 she named it as the book she is most proud of. Subsequently, she named the first story her best story and her personal favorite work.
During the 1990s McCaffrey made The Ship Who Sang the first book of a series by writing four novels in collaboration with four co-authors, two of whom each later completed another novel in the series alone. By 1997 there were seven novels, one old and six more recent. They share a fictional premise but feature different cyborg characters.
