I'm afraid you'll have to use console commands. Hit the tilde key (^) and type "help Meridia" without the "" . Then scroll for the spell book Id's and type "player.additem (spellbookid) 1" Replacing (spellbookid) with the Id the console tells you for the books should add one copy into your inventory.
