The Death Row Club (2026)
V A Vazquez
"A debut so accomplished and propulsive that it is guaranteed to be the thriller everyone is talking about. Twisty and addictive, I was on the edge of my seat from the first sentence until the last!"

Warning Signs (2026)
Tracy Sierra
"An isolated setting and a pulse-pounding fight for survival combine to make Warning Signs a truly stunning novel."

Here Lie All the Boys That Broke My Heart (2026)
Emma Simmerman
"What an addictive debut! Fresh, twisty and spicy, Simmerman's clever humour and absorbing mystery blend together to make something utterly bingeable and unputdownable, with the messiest of protagonists you just have to love."
