What is the author's style in How Proust Can Change Your Life ; Not a Novel by Alain de Botton?

De Botton has created what amounts to a self-help book, with wisdom founded upon a rather unusual source, Marcel Proust. It is clear that De Botton has plenty of affection and respect for the French author, and that De Botton's hope is to make Proust more accessible to a general audience. De Botton is an author himself and undoubtedly he has been influenced by Proust.
