He controls the variables. She embraces the chaos. Their collaboration could rewrite biology... or get them killed.

Dr. Aris Thorne lives by data and disciplines, meticulously analyzing life within the sterile confines of his lab. Dr. Lena Petrova chases discoveries in the wild, trusting muddy boots and fierce intuition over algorithms. They're academic rivals forced into the most unlikely partnership: co-leading a high-stakes expedition into the uncharted heart of the Amazon.

Their target: the legendary Flos susurrans, the Whispering Bloom – a mythical plant exhibiting impossible intelligence. But the journey plunges them deeper than expected, into a vast, terrifying subterranean world teeming with bioluminescent wonders and nightmarish creatures guarding ancient secrets.

Trapped beneath the earth, navigating treacherous terrain and hunted by monstrous predators, Aris and Lena must rely on each other. As calculated control clashes with impulsive action, their volatile friction ignites an unexpected, scorching attraction in the face of death. But survival isn't their only challenge. Shadowy forces monitor their progress, and the greatest danger might not be the alien ecosystem, but the human agendas manipulating them from afar.

Can Aris and Lena unravel the mystery of the Bloom and survive the hostile darkness, or will their mission—and the fragile, dangerous connection between them—be consumed by the savage world they've uncovered?

Dive into a thrilling blend of high-stakes adventure, chilling sci-fi discovery, and enemies-to-lovers romance in the first book of the Petal & Thorn series.
