I tend to have several books going at one.

Currently reading:

Historias de Cronopios y de Famas (mainly the stories in it that I didn't read before; it's quite hard going, my Spanish isn't really up to it, but it's excruciatingly funny so I enjoy it in small doses)

A Desert called Peace

Cumhnantan (yet again - I keep going back to that book)

Le château de ma mêre (It's 50 years since the last time I read that)

The History of Time: A Very Short Introduction

Derby's translation of The Illiad

Plus a couple of other Spanish novels that I'm half way through and go back to intermittently, because I was advised they would be good for my Spanish: Caperucita en Manhattan and Eva Luna - but only look at either of these for maybe an hour or two once a fortnight, or thereabouts.

Earlier this month finished reading 1636: The Kremlin Games; Sympathy for the Devil; A Beautiful Friendship; and rereading Le gloire de mon pêre and Cunnartan Cuain.

Oddly enough no maths or physics or CS books this month - that's unusual for me.
