In a sci-fi landscape overflowing with sequels, it's hard to find a story that not only gives a fresh view but also develops into deeper questions.
Trials of Sacrifice, the second book in JP Cawood's The Phoenix Gene series, does exactly that.
At the heart of it all is Jackie, a young woman whose "Phoenix Gene" makes her extraordinary: she is the one who can navigate the Slipstream, a strange, ethereal space where infinite timelines touch. Alongside her grandmother Beatrice and her father, she is on a mission to heal "infected" realities worlds warped by a relentless figure known as Alpha. This time, the task feels trickly simple: enter a timeline where Jackie was never born and where history took a darker, more fragile turn. What follows is a story that grapples with questions of identity, choice, and the crushing weight of responsibility.
This alternate reality stems from a single choice: Beatrice's refusal, years ago, to take a serum of immortality. That one "no" set off a chain reaction, erasing any chance of Jackie's parents to ever meet each other. Consequently, Jackie herself never existed.
To stop Alpha from carrying out a genocidal plan that would annihilate billions of lives, Jackie must infiltrate the Hampshire Academy as a 17-year-old student, navigating a world that feels familiar but is not her own.
What makes this book resonate is the way Cawood explores the revelatory experience of discovering yourself through time and experience. The mission isn't just about defeating a villain; it's about mending a broken probability. And the novel makes you feel that some repairs demand more than just courage they demand pieces of yourself you never knew you could offer.
At the emotional core of the conflict is Grace Claudi (Jackie's mother) who, in this timeline, is a lonely, privileged student trapped in a toxic relationship with Feraz. He is arrogant and dismissive, and treats anyone considered by him "inferior" less than garbage. Worse still: Feraz has been secretly producing a cheap version of the immortality serum, and its side effects are cruel. Every time he uses it to regenerate, Grace ages prematurely; her vitality is drained so he can remain intact.
It is a story of toxic love that darkly mirrors real-world exploitation disguised as devotion. Cawood does not shy away from this cruel reality; witnessing Grace slowly realizing the horror of her own life is painful and painfully close to our own reality. Her desperate need to believe in a "happily ever after" becomes a portrait of how love or belief can blind us even to the harshest truths.
The situation reaches a breaking point when Feraz senses something strange about Jackie and tries to kill her. This brush with death only strengthens her resolve to complete the mission. This is the "trial of sacrifice": a moment that demands an act of destruction to prevent an even greater annihilation. The moral ambiguity is not glossed over, and the narrative refuses to offer easy answers, presenting unsettling consequences that do not simply disappear.
At its core, this is a book about facing your deepest fears and accepting that some losses are irreversible. And the scars left behind? They remain, and we must learn to live with them. Cawood's narrative is concise and direct, prioritizing dialogue and action over lengthy exposition. Though she slows the pace just enough to let the tension breathe before the climax.
The characters are rendered so vividly that you feel as if you already know them. Despite the fantastical elements, certain situations feel uncomfortably real, strengthening the reader's connection to the characters. The way the multiverse and its various situations interact adds layers of suspense, making each twist land with impact.
Trials of Sacrifice rewards readers not just with excitement, but with genuine reflections about life. It is a story about love, loss, and the impossible choices we make for the people we desperately want to save. This is a series that grows bolder and it will leave you eager for what comes next.
