There were two mighty fine reviews of Solaris books in the Guardian recently. The first write-up is of Keith Brooke's The Accord:
"Brooke's fifth science-fiction novel is an intelligent examination of the technological possibilities of VR and a brilliant dissection of how individuals and society will change when freed from material bounds. The Accord is not only Brooke's best novel to date, but one of the finest to broach the subject of virtual reality."
And secondly, a lovely review of The Solaris Book of New SF 3.
"this series goes from strength to strength... there isn't a dud in the entire collection."
