Ocean of Ink

She can sense emotions. He's trained to be emotionless.

Wren's quiet life is upended when her brother's body is delivered to her family's estate by the elite academy he was attending. Consumed by grief and bound by a past debt, she goes to the Obsidian Academy to uncover the mystery behind his death and avenge the only person she's ever trusted.
A deadly forest surrounds the dark halls of the exclusive university, but the competitive, bloodthirsty students might be more vicious than the nightmarish creatures that haunt the woods. The most conniving of them all being Castien Valengard, the only one whose emotions Wren can't sense. And a man she believes is connected to the secret society her brother was a part of.
Wren devises a plan to uncover Castien's role in her brother's death, and in the meantime, works to balance her studies and her secrets. Then: another student is killed. Stuck on the island with no way out, Wren must find her brother's killer before she turns into the next victim.
