It is the second book in a duology, so yes, it is the end of the series. The first book is called Given to the Sea, and Given to the Earth wraps it up. Thank you so much for your interest in my work! If you follow me, you'll find various short stories and writing prompt responses to read. I'd be happy for any feedback, I appreciate it! Thanks so much, you made my day! (Sorry, I only just saw this.)
