a repost of what i wrote as a wrong answer to an inquiry about room raid keys. the answer is actually about finding the books so here you go:
no they are out, just hidden
click on specialty at the top of the mall, not any of the drop down menus, just the speciality link, that should display the 13 and 5 packs for you
it is where nox keys also are, its also.. casused alot of problems on NC chat too.
otherwise here is a direct link too http://ncmall.neopet...cat=#Speciality The Case of the Missing King Adventure Book 13-Page PackThe Case of the Missing King Adventure Book 5-Page Pack
13 page packs are 1200 NC
5 page packs are 500 NC
on sale through to 22nd march (retires the moment it turns 23rd march)
the bonus for activating each set of keys is Lulus Satchel you only get 1 per pack of keys but remember any unused pages are forfeited and you cannot redeem more than prize a day so doing 3 x 5 pks would get you 3 satchels but you would be paying 300 NC extra for 2 pages you can't use.
these are not readable books, and act the same way widgets and tokens work for wonderclaw and jubjub power bounce, in that they can be gifted through NC boxes, and need to be activated to be used, and disappear once you activate them.
