I think this is a beautiful solitaire game. When you make enough money in the game, you can purchase amulets from the shop that will help you; if you hover your mouse over each amulet, it will tell you what the purpose of each amulet is. There is also a place in the shop where you can buy more wild cards, which can be a big help.
The "book" that is referred to is that small golden "book" at the top lefthand corner of your screen when you are playing a game of solitaire.
