For fans of Iain M. Banks, Alastair Reynolds, Peter F. Hamilton, and anyone craving a space epic filled with sprawling civilisations, ancient riddles and galaxy-spanning stakes. When machine sentience in the galaxy is threatened, an ancient species is revived. Kera and Diyan are among the last of their kind, aboard a starship bound for deep space. They’re not survivors. They’re not soldiers. They’re resurrected—from extinction. A last resort, sent by their near-omnipotent reviver, Tapache, to discover the origins of a weapon capable of obliterating machine sentience. Unfortunately, they’re not the only ones investigating. An ambush by an enemy fleet leaves Kera missing and Diyan stuck in an escape pod. All hope seems lost. That is, until the weapon’s source appears—although it’s nothing like anyone thought. It appears impenetrable… until Diyan becomes hopelessly stuck in its gravity well. The source’s galaxy-spanning repercussions, not least for machine intelligences, are far greater than anyone realises—except perhaps for Kera, who entered first. Why were they really revived? And how exactly did they become extinct? Cunning, mind-bending, and rife with mystery, this is an epic for those who know the galaxy is as dangerous as it is wondrous. BOOK 1 OF THE TAPACHE'S PROMISE TRILOGY, SET IN THE WANDERER UNIVERSE. "Echoes of Gravity is a brilliant example of an accessible, modern, sci-fi adventure/mystery story. As the first book in the Tapache's Promise trilogy and a new entry in the Wanderer Universe, this book offered an intriguing introduction to a new sci-fi world and saga. The main highlight of this book was the superb worldbuilding. I can tell that a lot of research has gone into constructing this Universe as there were references to the laws and theories of physics such as string theory. The unique creatures/species & the social structure are explored in detail, but simply, so there is no confusion. ... The pacing of the story begins fairly slowly as we are introduced to the world. It then picks up considerably (when things start to go wrong) and doesn't slow down from there. James Murdo's writing is descriptive enough to paint a clear picture of each scene whilst not being weighed down with jargon. The writing in the opening chapter did feel quite repetitive, but I think it was intentional as this was the only section of the text that felt this way. This book ended on such a great cliffhanger! It left me questioning everything. I love when books end this way and am so excited to read book two in this trilogy! I utterly enjoyed reading Echoes of Gravity. The adventure I was taken on was captivating & I am very excited to read the sequel! This book would be enjoyable as an introduction to sci-fi, or for fans of the genre, looking for a modern, space-opera/mystery adventure." - Goodreads reviewer (2021) James Murdo was born and raised in London, where he still lives. He graduated from university with a Masters degree in Physics, which added fuel to his early love of science fiction. AVAILABLE BOOKS By James Murdo ALL SET IN THE WANDERER UNIVERSE.

Though she could not see it, she could sense Echoes of Gravity, swirling nebulously around her, never revealing itself but always there. She gripped the device tightly in her hand, hoping it was enough; that, somehow, Echoes of Gravity would understand it for what it was. A receptacle for knowledge. As soon as she returned to Sunsprit, she had felt the inexplicable desire to travel to Echoes of Gravity's hidden dwelling. It had called out to her, drawing her back. She had been called before, but this time was different. She had always had her opinions about Echoes of Gravity; her own theories and musings, just like everyone else who knew of it. But now, for her, some of those thoughts had been validated. Echoes of Gravity was an external presence, with a will of its own. She could feel it. Thoughts came to her, lifted from the recesses of her mind. Echoes of Gravity was weaving a story for her, from her own memories, as though it were a lonely, orphaned mind, with no memories of its own. Her palms dripped with sweat as she continuously rolled the device about in her hand, reminding herself why she was here. It probed...and probed...and probed...exploring every part of her mind, weaving its tale. The Source. Tugs. Vaesians. Roranians. Veilers. Great Ships. Tapache. Many other words and concepts she did not understand. Everything was connected, the answers tantalisingly close. Echoes of Gravity was too different;
