A cursed seed. A stolen father. Two sisters who refuse to give up.

When the Spider Empress marks Dill Thistlegale as The Seedling and then drags her father into the depths of Webmura, she and her sister Sage must cross worlds to bring him home before he’s lost forever. And these aren’t your average sisters-they’re part plant, part human, and 100% determined. Their quest leads them through enchanted forests, an unfamiliar human world, and the dangerous web-strung city of Webmura. All the while, the ancient feud between plant-folk and insect-kind threatens to unravel everything they love. But saving their father will take quick thinking, fierce roots, and faith that refuses to wilt.
