A review by bookwyrms_shelf
The Duke and the Disciple by Sarah M. Cradit

5.0

This was intense, and dark, and wonderful. Aeslyt has been working so hard to continue her life of research. Of course, the Reliquary wants to control it all. Rahn has also worked hard to keep the research within his grasp, and not let the Reliquary completely take it from them. Aeslyt's sister in law started it, and they've been trying to hold on as long as they can. 

When they're given a scandalous curriculum on top of threats of a war, Aeslyt and Rahn do what they can to discreetly conduct their research together. Under the cover of astronomy, and with a bit of actual astronomy, they fall deep into their research, and deep into one another. 

This was a whirlwind of action, desire, and realizing what it means to love.
