≈ Martin's Dance with Dragons, 120 pages in;
≈ Hobb's The Golden Fool, 250 pages in;
≈ Scalzi's The Last Colony, 2/3 through;
≈ Asimov's Caves of Steel, no idea where I am there.
Hobb's book is... decent. Readable, but not much more.
To say that everything else is mediocre so far is a kindness.
I have to say that Scalzi's The Ghost Brigades, the book that comes before The Last Colony (Old Man's War Trilogy) was to me an excellent read. Recommendable to everyone who likes some depth to SF.
