"Love grotto" is where he sticks his things for me to get the good feels, not the place where we do the dirty, I assume. It would be nice to have a house big enough to have a love grotto, but then again, don't be bound by these things (be bound by your...I'm going way off topic from what I dropped in here to post...)
Discworld Reading Guide" by Krzysztof Kietzman. It also has versions in other languages, accessibly enough: [link]
It seems useful because it breaks the books down by character/topic, so you know what order to read those in, as well where plotlines overlap.
I need to look and see where the few I've read lie, and use it to help me choose my next purchases--good use for my $5 credit I got for buying a new Nook, if it hasn't expired yet. I bought a new Glowlight. Irritatingly you can't put in memory (which was great for transferring fic), and it has no reading buttons. The screen is more sensitive so it's easier to advance pages with my left hand (as is my wont), but I really liked the option of clicking through--I'm of two minds about touchscreen and e-readers, to be honest.
The screen quality is beautiful. Although my older Glowlight (the one that looks like the version without the light) is usable inbetween lockups, I instantly decided to make the new one the one that travels, and even bought it a cover (I rarely by covers/cases).
I'm sad it's probably the last.
