Not Sure If I Like The Alternate Timeline Format

The cover art is striking and conveys the story well. I liked the premise, but I am not sure what I think about the alternate timeline format. The dual perspectives, that of Signe in the past, and David in the future, are compelling in their own right. This timely story addresses an issue that is very current, that of the dangers surrounding climate change. I would be interested in reading more because the more I was accustomed to the format, I became more engrossed in both Signe's and David's stories.
