This novel, brilliantly written by Annie Kaufman and Megan Spooner, is the first of a trilogy chronicling the journey of different human pairings as they face the terrain of various planets together having only each other to rely on. I thought this book was very well written as a result of it having 2 view points for the reader to understand the story from. Each of the main characters, Lilac and Tarver, had their own point of view and each chapter switched from one character to the other. These differing points of view allows the reader to get a glimpse into the respective characters mind and why they made certain decisions. The authors did an amazing job painting a clear picture of the planet the characters were on and the emotions the characters were feeling. The descriptions were so gripping that I felt, as a reader, that I was transported into the books universe. In addition, the authors did a marvelous job creating two different voices that told the story, it was clear in the narration from both of the characters the differing feelings and experiences that speak to the story as a whole. The novel chronicles the emotional turmoil the characters face as they are marooned on a deserted planet, one being an heiress and one being a soldier, the book gave a very interesting take on what one goes through when one can only rely on the other person. The story has equal amounts of humor and action which was important to the development of the plot. I thoroughly enjoyed this novel because it took the reader on a journey that, while being terrifying for the characters, was very vital in the character development of both characters. The format of the book kept things very intriguing, at the start of every chapter there was a dialogue from an interrogation taking place in the future that really analyzed what happened in the previous chapter which I found very helpful. As I reached the ending of the book, because of Lilacs journey, I couldn't help but question "is ones soul so trivial that we are in fact replaceable?" The book left me craving more of the intriguing world, causing me to start the second book immediately, I highly recommend this book.
