Skios by Michael Frayn
Perfectly well oiled comedy of errors.
The Hydrogen Sonata (Culture, #10) by Iain M. Banks
Solid but somewhat routine Culture installment.
A Wanted Man (Jack Reacher, #17) by Lee Child
Solid Reacher installment.
Some Remarks: Essays and Other Writing by Neal Stephenson
Excellent collection of articles and a couple of short stories. Worth reading just for the Wired article on the technology and politics of submarine cables.
