An epistolary novel is a novel written as a series of documents. The usual form is letters, although diary entries, newspaper clippings and other documents are sometimes used. Recently, electronic "documents" such as recordings and radio, blogs, and e-mails have also come into use. The word epistolary is derived from Latin from the Greek word ἐπιστολή epistolē, meaning a letter (see epistle).

The epistolary form can add greater realism to a story, because it mimics the workings of real life. It is thus able to demonstrate differing points of view without recourse to the device of an omniscient narrator.

Now, now, Bowie. You know the first rule of authoring is that the author personal is third party. 

Don't listen to his psuedo-intellectual gibbering. 

And it's not the duty of a friend to prevent a climax. 

Hold on a minute - no climax and they've all to humph me? 

I don't  like where this is going.
