Weert's book is an advanced foray into the use and pricing of exotic options. Where these are broadly defined to be those options whose payoffs can't be duplicated by normal options.

The main dependencies of option pricing are studied. Above all, the interest rate. Though for those knowing calculus, the text says that this is merely the partial derivative of the option price with respect to the interest rate. See how simple life gets, if you know calculus.

Option strategies like call and put spreads are explained. These may be familiar terms to you, if you have used normal options. But elaborations arise when dealing with exotics.

The text seems to deliberately minimise the complex maths involved in modelling pricing. Perhaps out of a desire to attract a broad readership?
