The Best
Primo Levi’s The Periodic Table is a humane and inspiring meditation on humanity through the lens of chemical elements. (Review; get it here.)

Honorable mentions
The anthology So Long Been Dreaming: Postcolonial Visions of the Future brings forward a number of important voices to the spectrum of sf writing. (Review; get it here.)
A lot of people seem to disdain the first of A.S. Byatt’s Federica novels, The Virgin in the Garden, but I was fascinated and amused by it. (Review; get it here.)

The one you haven’t heard of
C.E. Murphy has not (yet) had the recognition that she deserves in terms of winning awards, yet she consistently churns out good to excellent fantasy (and occasionally sf). You could do worse than start with her Atlantis Fallen. (Review; get it here).

The one to avoid
Terence Dudley’s novelisation of his own Doctor Who story, The King’s Demons, is very disappointing. (Review; get it here.)
