The Book Shop Boarding House Murder

Nineteen-year-old botany major Wren Callahan just wanted to survive her scholarship, foam enough oat milk lattes to make rent, and maybe figure out why she can't stop thinking about the cafe's infuriatingly witty barista.
Then the university's most hated dean drops dead mid-sip of her latte, and her whole life turns into a crime scene.
Wren knows two things the police don't: the poison wasn't in her latte, and someone wanted it to look like it was. As the only person who noticed the telltale scent of monkshood before he hit the floor, she has days to prove her innocence. While her scholarship funding freezes, her found-family roommates start looking less like allies and more like suspects, and the boy she's absolutely not supposed to be falling for turns out to be the dead dean's estranged son.
Between the crooked shelves of a labyrinthine bookshop boarding house, a missing journal full of academic blackmail, and a secret society hiding behind ivy and old money, Wren has to use the one thing she's actually good at, knowing her plants. She needs to catch a killer before they decide she knows too much.
Cozy mystery. Dark academia edges. Slow-burn romance with a fake-dating twist. Found family that might just be full of secrets.
