A library book I borrowed in the mid to late seventies. Have been trying to find it on and off for years. The story goes something like.....
A female Captain of an enormouse spacecraft is persueing a fugitive, who tricks her into flying too close to a star, but instead of destroying the ship, it breaks up into thousands of self contained individual ships. These are scattered widely, and our Captain finds herself alone, isolated with no way of making contact. However after an indeterminate length of time, she is rescued by the the survivors of the original ship, who have reassembled and searched for her since the disaster. She notes that not all the component parts of her original ship have survived.
I think I must have had to return the book before finishing it as thats all I can remember. Any information would be gratefully recieved. Thanks.
This sounds like AE van Vogt's 'The Mixed Men' aka 'Lost, Fifty Suns'. At one point, there is indeed a female hunting for an entire civilisation of 'fugitives' who is led into the path of a supernova which nearly destroys her ship. From what I recall the rest of your synopsis seems quite accurate. van Vogt's work was widely published in the 70s (although this is a 'fixup' novel based on short stories written in the 1940s)
