Nick Lappos: Engineer; polymath; bibliophile; web wizard... thanks for the link. I found two copies of the sequel, regrettably far away from the five-dollar end of the stall.
Hilico: You can have it when I've read it. Send me a PM with address. Might be a while... 36 days for delivery.
Hueywsh: If you still haven't found one, I'll pass it on to you in turn. We'll start a pprune lending library.
PS: Apart from Weapon, there's also mention of a work of fiction by the same author called 'Solo'.
