Some of the events are fantastic and improbable, but Sawyer handles the pace well. A great ending and a satisfying read.
The final book of the trilogy, and certainly the weakest in my opinion. In far too many places this is less a work of fiction than an ideological treatise wrapped in fiction, and not a good job of packaging. Issues were belabored far too long and rather condescendingly far too often. The main character, Mary Vaughan, seemed to be slow witted for someone who is supposed to be a world renowned scientist, taking an extremely long time to figure out basics of the Neanderthal society (and sometimes having them explained very slowly and repeatedly) that are obvious to a reader paying even moderate attention.
If you fell in love with the earlier books, then naturally you will want to read the final one. But if you thought they were only okay, then you can skip this one and probably not miss anything.
In this concluding volume of the trilogy, the improbable love story between Neanderthal Ponter Boddit and human Mary Vaughn comes to its fruition. Some of the events are fantastic and improbable, but Sawyer handles the pace well. A great ending and a satisfying read.
