In the Dan Dairies we get to see Dan’s PoV. It in point of view that we see how it is for him and his friend Fank. It mostly the journey of Dan and how he helps his loves one and including Hank.
It starts out with Dan and transition. What he needs to do and help the main man up head and what need to direct one person path to her destiny. Will Dan succeed or will he not? To me this is more a summary of the 3 books that are before this one. It goes over summary of some of the big events that Hank has to deal with and Dan having to convince Hank (Olivia Henry).
Frank is a part of this, with Dan is it mostly about Dan and though his point of view. If you have not read the Beyond Trilogy. This is only the summary of it. This really conflues the series and helps define some of the holes or to see Dan and his view point. If you want the story and details of Olivia and Finn story, you will need to read Beyond Trilogy - books, Beyond Believing, Beyond Love, Beyond Forever.
The author does a really good job of this. She really show the Dan’s life in the afterlife and his point of view well.
