Meet Me at Apogee by Bill Johnson
Great surprise from this older story. Classic adventure with black hole time dilation combined with spaceship exploration.

Farrar Reinfeld lives in a habitat orbiting a black hole. He has a small spaceship and earns a living by taking “dives” close to the black hole, for research or excavation missions. The constant time shifts puts his life in a weird state, as culture and langauge change drastically around him. One day he more or less gets forced into doing a mission with someone looking for survivors on a spaceship near the black hole. The man who hires him has ulterior motives and of course things go haywire.
The plot that follows is well paced action adventure, but what I enjoyed the most was the world building and rich characterization. Reinfeld is a tragic fate with how displaced in time he is, and the setting with a habitat orbiting a black hole could easily have laid the groundwork for an expanded series of stories, but kept neatly at this nice entertaining story.
