A sapphic obsession. A sketchbook full of ghosts. A love story that watches back. Shizuka keeps to herself. She draws strangers in cafes, catalogues city shadows, and pretends not to notice the girl who always sits two tables away. But when sketches begin appearing that she didn’t draw, and camellias start turning up in places no one should have access to, Shizuka realizes she’s not just being watched. She’s being studied. Memorized. Quiver in the Dark is a slow-burning, psychological queer romance wrapped in fear, longing, and tender invasion. For readers who like their love stories haunted, their heroines trembling, and their obsessions mutual.
