This book was part of an Indie Fantasy Bundle from https://storybundle.com/ The narrative has the form of an epistolary book, interspersed with journal entries, and follows the points of views of twelve-years-old Em, living in a seabound small community on the Mexican Gulf and an adult woman, Kaya, imprisoned on a Asian isle volcano for her political views. Through a fateful message in a bottle, they start corresponding. I had a little hard time accepting how the message in a bottle reached a person detained on a prison suspended on a volcano, but then all the landscapes presented and the straits shown are both real-like and fantastic.
I lost interest somewhere in the middle of a Kaya's journal entry around page 40. The premises are nice, and this is not the kind of fantasy book I usually read, but I wanted to give it a try. Probably all the local lore and circumstances described in first person just didn't manage to catch my attention, and the beginning was like being dropped in medias res, to see both the main characters' lives and struggles in snippets just didn't do it for me, even though this is not the first book I've read with this narrative scheme. No rating, I didn't finish the book, nor I read enough to comment on the writing style or plot/character development.
