Foundation's edge

Doesn't have the same zing as the original trilogy, but introduces the most memorable characters of the series. The characters are logical and consistent and you can't put the book down for wondering what's going to happen next. Some spice, another thing that makes it not as good as the original trilogy.

Age range: 16+
More mature content than the rest of the series, mostly used as character development for the protagonist, but almost nothing compared to any romance book. There are complex philosophical themes throughout that would be incomprehensible to most younger readers.
