Third Time's A Crime by Laura Greenwood

Messing with black magic has serious consequences.

Betrayal is a strong word, and now I'm being accused of it. 

At least I'm not the one in custody for a crime I didn't commit, though that's caused its own problems. If I'm going to follow my heart, I need to prove one of my warlocks is innocent. The problem is, I don't know how to do that without condemning myself. 

-Third Time's A Crime is book three of Grimalkin Academy, an urban fantasy academy series featuring two best friends, lots of kittens, and a low-heat poly romantic subplot.
