Use of Weapons
by Iain M. Banks (Orbit, 1990); audiobook read by Peter Kenny (Isis, 2013)
A grand, sweeping, poetic SF novel, abstruse at first but gradually taking form as its two narratives (one told start-to-end, the other end-to-start) take shape and interweave. Disorientation becomes nebulous understanding becomes full engagement as Banks drives towards a cleverly concealed denouement.
