Hateful Regent by Helen Scott

Finding out who murdered my sister was supposed to be easy…
The Boys of Ascendance Bay are more complicated than I ever imagined. Between what Jude told me and the creepy notes that I’ve found in my room I’m beginning to wonder if there’s more to my sister’s death than I first thought.
Melody is pushing harder for me to find the evidence we need to take our revenge. Add to that pledging Pi Ep and the Regents taking an interest in me, and my already full plate is starting to overflow.
It doesn’t help that my icy cold heart is trying to beat again for two of the guys we suspect had a hand in our sister’s murder.
I’m too damaged, too lost in my father’s web to fall for them though. If I did it would start a war between our families the likes of which has never been seen before, and who knows if we would survive the fallout?
