Elegance in Exile: From Alchemy to Luxury with My Ardent Knight

Raised to be the perfect consort to the crown prince, Anrietta Augustia’s careful plans for the future come crashing down when her fiancé publicly breaks off their engagement, calling her a foul witch and exiling her from the kingdom. For a sheltered daughter of a duke like Anrietta, it’s essentially a death sentence...but fate has one more twist in store. The crown prince’s dramatics awaken something buried deep within her: memories of her past life as a mighty sorceress, along with a powerful gift waiting to be used. With her newfound knowledge and power, Anrietta decides to set out and start anew. First, though, she'll need a servant—one who will never betray her the way those she trusted did in this life...or the last. Source: J-Novel Club
