Perfect for you if...

You enjoy dark academia with actual stakes and a central mystery that drives the plot forward, not just vibes and house politics.
You want slow burn romance where the emotional tension between two people matters more than their first kiss, and you're patient enough to wait for it.
You appreciate unreliable narrators and the tension of a protagonist who uses deception to get answers while slowly revealing her own secrets.

Maybe not for you if...

You need a fast-paced mystery where clues arrive regularly and suspects feel logical. The pacing here serves the romance and atmosphere first.
You prefer romance that's the main plot rather than interwoven with a darker investigation. This one keeps you guessing about both simultaneously.
You're sensitive to grief portrayed in visceral, ongoing ways. Wren's loss colours everything and doesn't get neatly resolved early on.

About this book

Wren can sense emotions, but Prince Castien Valengard is an exception—his feelings remain hidden from her. When her brother's body is delivered to their family estate from the Obsidian Academy, Wren is driven by grief and an old debt to infiltrate the exclusive institution and discover what happened to him. The academy sits on an island surrounded by a deadly forest and magical waters. Its competitive students prove as dangerous as the nightmarish creatures in the woods. Wren suspects Castien is connected to a secret society her brother belonged to and devises a plan to uncover his involvement in her brother's death while managing her studies and concealing her true purpose. When another student is killed, Wren becomes trapped on the island with no escape. She must identify her brother's killer before becoming the next victim. Ocean of Ink is the first book in a slow burn romantasy duology set in a dark academy.
