6) Fables & Reflections by Neil Gaiman (Sandman vol 6) – thought-provoking as always, but a bit episodic.
7) The Music of the Primes: Searching to Solve the Greatest Mystery in Mathematics, by Marcus du Sautoy – interesting story of the humans behind the maths, but I would actually have liked more equations. My brother almost got mentioned twice (his current boss, and his student who won a prize for cryptography). But I must buy an actual textbook on number theory if I want to be serious about this interest.
8) Brief Lives by Neil Gaiman (Sandman vol 7) – my favourite of them so far. Only thing that spoils it is the artwork getting a bit dodgy around Chapter 6.
