They are rune books, not "ruin" books - but I've got an extra Trammel THB-system set that are reasonably accurate, that were the THB house's original book set before I replaced them.
PM me if you're interested in them.
The THB house has full THB-system and Goodman-system books (though the fel THB maps and the Goodman maps haven't been updated in at least 6 years) locked down and set for public use, at the Compassion Desert Crossroads in Trammel - feel free to copy them or just use them.
