Shutter (vol 1): Wanderlost - Joe Keatinge

Okay so there's this girl and apparently she was once this big-shot explorer, but now she's retired for some reason despite not even being 30, and she lives in this magical world that has some similarities to ours, and she has a best friend and some sort of robot cat which we know nothing about, and her dad's dead (which is sad, but we didn't know him), and people are trying to kill her for some reason, and apparently she has some unknown siblings who are also trying to kill her--okay the point is there's a lot of stuff happening here, but nothing actually happening in the sense of helping us understand what type of the world we are dealing with, who the main character is and why should we care about her, etc., you know, basic plot points. This seems like something I would like, but first I have to have some clue as to what is going on. shutter
