BLURB
Having survived the attack led by her sister, Cara is ready to move on.
A new city means a fresh start and a chance for her and Brown to live together, as equals.
However, the perfect façade of the Amex community hides dark secrets.
With a nightly curfew and a mysterious scientist in charge, Cara is convinced all is not as it
seems.
As her doubts grow, so do the arguments with Brown. And with Myla still alive and
looking for revenge, it’s not only the danger from inside the city walls that threaten to
tear her world apart – forever.
Ultimately, she will need to make a choice: protect her family at all costs, or save
herself.
AUTHOR BIOGRAPHY
Hetty Waite lives in Derbyshire with her husband, daughter, and cavapoo.
A former teacher, she spent many years sharing her love of stories with teenagers in the classroom before turning her own ideas into fiction. It was during the pandemic, while on maternity leave, that she finally found the time to write her first novel.
After initially self-publishing, a chance meeting with a director from Spellbound Books Ltd at a writers’ school changed everything. Impressed by her debut, they offered Hetty a three-book deal for her Young Adult dystopian series, The Chromosome Trilogy. The first instalment, Mutate, was re-released in 2024, followed by Evolve in October 2025.
When she’s not writing, Hetty tutors English, marks exam papers, and enjoys life in Derbyshire with her family and their lively cavapoo.
REVIEW
I still remember finishing Hetty’s Mutate and sitting there for a moment, wondering how on earth she was going to top it. That book was a breathless, clever mix of sci-fi and human emotion, with characters who felt raw and real. So when Evolve arrived, I already had high hopes. It didn’t disappoint.
From the very first page, Hetty drops you straight back into the chaos. The Wilders are everywhere, danger presses in from every direction, and before you can blink, you’re thrown into a fight for survival. The pacing is bold and confident, showing a writer who knows her world inside out.
At its heart, Evolve is about family, love and loyalty set against a backdrop of mutation and rebellion. Cara, Brown and their baby, Xyla, are trying to build something resembling peace in a world that has forgotten what that word means. But just when you think they might get their happy ending, the ghosts of the past catch up with them.
The emotional stakes are huge. What impressed me most is that Hettie never loses sight of the people behind the science. Even as she explores genetic mutations, strange serums and terrifying hybrid creatures, she keeps the focus on human feeling. Cara’s inner conflict about whether to trust the mysterious Melody or resist her offer feels deeply believable. It’s a moral struggle that mirrors real-world dilemmas about power, control and identity.
Brown continues to be a wonderful counterpoint to Cara’s determination. His calm practicality balances her intensity, and their relationship has matured beautifully since Mutate. The small scenes between them are some of the most touching. Amid the noise of gunfire and the roar of creatures, there’s still time for tenderness, and that makes the story matter all the more.
One of my favourite elements of this book is how it expands the world. We move beyond Galex into Amex, a supposed safe haven where everyone lives in harmony. At first, it feels like a dream come true. But as Cara quickly discovers, perfection often hides corruption beneath the surface. The way Hettie reveals the city’s secrets is slow and deliciously tense. By the time the truth comes out, you’re gripping the book, muttering, “I knew it,” even as your heart sinks.
Hettys writing has grown more confident since Mutate. The action scenes are sharper, and the emotional depth has increased tenfold. She handles multiple points of view with clarity and grace, especially when switching between Cara, Brown and the secondary characters like Pan, Becka and Striker. Each voice feels distinct, giving the story a layered, cinematic quality.
Speaking of cinematic, this book would make a brilliant series. The imagery is vivid, from
the eerie glow of the Reptilius Centre to the smoky ruins of the marketplace. You can almost hear the crackle of flames and the thud of heavy boots on metal stairs. It’s science fiction with grit, but also with beauty.
What also stands out is how Hetty uses transformation as metaphor. The mutations, the Sub and Y dynamics, the constant battle between evolution and extinction, all of it reflects the human urge to survive and adapt. Underneath the scales and claws lies a very real story about how far people will go to protect those they love.
Without giving too much away, the ending is powerful. It balances tragedy and hope in just the right measure. There’s loss, yes, but also a sense of resilience. Cara’s journey, especially as a mother, struck a chord with me. Her strength isn’t portrayed as perfection; it’s built on fear, sacrifice and love. That’s what makes her unforgettable.
I also appreciated the small flashes of humour and warmth. Amid all the darkness, Hetty reminds us that life still holds light , a baby’s laughter, a shared glance, the quiet moments before dawn. It’s those glimmers that make the world of Evolve feel real.
Hettie has created a universe that’s as emotional as it is dangerous. The Chromosome Trilogy so far has been an exploration of what it means to be human in a world that keeps changing faster than anyone can keep up. Evolve builds on everything that made Mutate special and pushes it further, deeper, and darker.
By the time I turned the last page, I wasn’t just impressed. I was moved. I cared for these characters, and that’s the greatest compliment I can give any author. I can’t wait to see how Hetty wraps up the trilogy. If the first two books are any sign, the finale is going to be extraordinary.
If you enjoyed Mutate, you’ll love Evolve. It’s fierce, heartfelt and completely gripping. Hetty doesn’t just write about evolution; she shows what it looks like when a writer evolves too.
