1979’s Maeve is the fourth book in Jo Clayton’s Diadem series; it’s the second book in which lead character Aleytys gets to wear clothes on the cover.
Determined to find her mother’s lost home world (which is somewhere towards the galactic core) and her own kidnapped baby, Aleytys funds her way from star system to star system by working her passage. Her latest ride has reached its core-ward extreme. Aleytys disembarks on Maeve to hunt for a ship heading in the right direction.
There are one or two minor complications.
