Emma Grove's comics memoir, The Third Person is a veritable brick of a book, running over 900 pages, (nearly) all laid out in a uniform 8-panel grid.  Roughly half of the book takes place in a therapist's office, so the action on the page is primarily of the verbal variety.  The adventure that is at the core of the story largely takes place in the protagonist's head, as s/he works with their therapist – in, as it is revealed, three separate identies.  There is a  mystery at the core of this story – which can be read as a sort of detective story – as Emma, along with her alternate identies, Ed and Katina, work together with the therapist to discover the root trauma(s) of this situation and whether or not it should be diagnosed as DID (Disassociative Identity Disorder). 

The Third Person is likely to be of special interest to those who are or have been in therapy, especially when focused on recovering from trauma – as well as to those who would like to learn more about the therapeutic experience and/or are considering entering into therapy.
