randonly occurring Discworld novels

Browse Source 
Give 'novel' a 1 in 1000 chance of being created in place of each
random spellbook (except for hero's initial inventory and NPC
priests' monster inventory and divine reward for prayer--those all
force regular spellbooks; statue contents aren't among the
exceptions--those books can now be novels).  Shop inventory (where
first book or scroll shop created is guaranteed one novel) hasn't
been touched.  If there is any other special spellbook handling
somewhere, I've overlooked it.
