Tart of Darkness — Denise Swanson

Right when Dani thinks she's hit a dead-end in her career, she unexpectedly inherits an enormous old house in a quaint college town. This gives her the perfect opportunity to pursue her true passion―cooking! So Dani opens Chef-to-Go, preparing delicious, ready-made meals for hungry students attending the nearby university, as well as providing personal chef services and catering events for the local community. To help support her new business, she opens her home to a few students, renting them rooms and becoming almost like a big sister figure in their lives.

But just as Dani is relishing her sweet new life, the friend of one of her boarders is murdered, and Dani becomes one of the primary suspects! She'll have to scramble to clear her name and save her business before the killer reappears―perhaps to silence the new chef forever.
