   Summary

   Sage Knight thought working under mutant tech genius Donatello Hamato would be her ticket to grad school, not a lesson in temptation. He’s brilliant, arrogant, and infuriatingly hot, with eyes that see through her and a voice that makes her forget why she’s there. She came for the science, not the sparks—but in a lab full of secrets and tension thick enough to cut, staying professional is starting to feel like the real experiment.
