Just got from the Free Shop. But there's none in shops or trades, as far as I can tell. Any ideas on price?

Seasonal item according to Subetalodge, so you might want to sell it before easter... It's an unpriced book, so you'll probably be able to find either early book drive achievement seekers or hoarders that might be interested. As for a specific price...start as high as you'd like and work your way down :P

One in auctions for 10M at the time being.

Locking, as this item is priced in the shop search now.
