Senna Evans has always been drawn to things that kill. Immune to the deadliest plants in her garden, she has spent her life cultivating beauty with lethal roots and keeping her head down. But when her wedding night ends in betrayal and a public execution, the quiet life she fought to protect is torn apart. Dragged into a world where fae bargains carry the weight of law and secrets are worth more than lives, Senna becomes entangled with a prince whose charm hides something monstrous. To survive, she must uncover the truth behind a forbidden book and the ritual magic that should never have been disturbed. As the line between hunter and hunted begins to blur, Senna discovers that some poisons are far deadlier than anything that grows in her garden. Survival comes at a price, and some prices cannot go unpaid.
