The novel “Transcendence” by Charles Sheffield was published for the first time in 1992. It’s the third book of the Heritage universe and is the sequel to “Divengence” It’s also part of the omnibus titled “Transvergence”.

The fierce Zardalu are back but no one believes it. Not even the testimony of a respected scientist such as Darya Lang, that of a Councilor and that of an android who can’t lie, are not considered. They need to find hard evidence so the heterogeneous group who stumbled into a group of Zardalu in stasis intends to find out where they ended up.

Nobody ever knew the location of Genizee, the Zardalu homeworld, and over the millennia passed since they were considered extinct no one found it. But no one had as much information as the group that met them and thanks to the new data they locate the area of space where to find the planet. The problem is that it’s a large space-time anomaly.
