Hero Returned | 
Received this via LT Early Reviewers. Sadly the map is at 90º so it's a bit small. Narrated in 1st person, past tense. It took me 6 chapters to realise that we're reading a books she's writing about her experiences (still getting into the story); 'omake' is Japanese for 'extra' and ch 6 has an omake with her discussing the writing with her co-authors.
I'm still getting the hang of this story but enjoying it so far.
Though it doesn't end on a cliff-hanger it doesn't link up with the prologue, which starts at the end with 'this is how I got here' 4mo
