Reader Reviews For Books One and Two
“If you are not familiar with Xanthe Walter’s work, you should check her out. She writes in such a way that you become part of the world right along with her characters.”
“In a dystopian world teetering on the edge of collapse, the slow, intense burn between Alex and Josiah is impossible to ignore. Every glance between them simmers with unresolved tension, every interaction steeped in history.”
“I’ve discovered a new writer with an imagination I can get behind… I found the writing riveting, the world-building exciting, if dark and dystopian, the character building afforded by the flashbacks brilliant, and the overall story highly engaging.”
“The world-building here from Xanthe is superb, her imagination creating a fully-formed and completely believable dystopian society that contains reflections of our own but is, at the same time, also totally unrecognisable… I’m so glad the other three books are all written and releasing each month because I can’t wait to find out all the secrets this impressive series is hiding.”
“This is my first book by Xanthe Walter and I know it will not be the last. It has everything I like in a book – action, suspense, a new intriguing world and fantastic characters.”
“So well written with a brilliant storyline and intriguing characters that kept me invested until the last page and left me wanting more! Highly recommended.”
“The chemistry between Josiah and Alex simmers with tension, raising questions of trust, grief, and forbidden desire. With sharp worldbuilding and emotionally layered storytelling, Xanthe Walter crafts a slow-burn thriller that pulls you deep and refuses to let go.”
“Xanthe’s writing is exquisite, knowing when to hint and when to reveal details, knowing how to grip me tight and keep me feeling deep feelings for the characters.”
“Once again, I was completely addicted to this book, and honestly could have kept reading for another 500 pages… I’m once again in awe of Xanthe’s ability to write rich, flawed, completely believable people…
THE GASP I GASPED at the plot twist! Maybe I should have seen it coming, but I was just vibing and it completely surprised me. I have a feeling it’s not the last twist we’re going to get in this series…”
“The slow burn of Joe & Alex does heat up in this book! There were definitely moments of questions answered & twists I maybe should have, but didn’t see coming! (I had such a strong reaction in the middle of the night reading that my husband woke up and I just had to try to explain it!)”
“Alex’s past continues to be absolutely gut-wrenching—hard to read, but incredibly important. And that plot twist?! I did not see it coming in book one at all and I loved it.”
“I have been amazed at the length of the story, and amazing detail the author has put into this huge, crazy story, to get us near to closure. I’m so excited for the next part. Bring it on! I absolutely loved reading this story.”
“Another absolute read for me!!!
I rarely enjoy a second book in a series like the first one, but this blew me away just as much as the first one did. The history of the characters and the time jumps into the past make so much sense for the development of the characters and to understand where they’re coming from.”
When you can’t decide whether to flee or face the music…
“Alex, you need to make this decision tonight. We have to get going before dawn if we’re leaving. If we walk into Inquisitus tomorrow, I can’t promise I’ll be able to save you.”
“I know.” Alex sat down beside him with a thump. “You and me, together, on the run… you have no idea how much I want that.”
“But?” Josiah squeezed his hand.
“I made a promise to Solange. If I leave…”
“Would Solange expect you to prioritise that promise over your own life?”
“No. Solange wouldn’t have asked me to do any of this. My mission is entirely self-imposed.” Alex gave a wry smile. “But it’s all that’s been keeping me going for years. I have no idea what I even am without it.”
“We can find out. Together.” Josiah leaned in to kiss him. “If you want me,” he added as he drew back, feeling suddenly insecure.
