A Sea Change: A Shadowhunters Novella by Cassandra Clare (Hardback)

A seafaring Shadowhunters mystery, following Matthew Fairchild as a journey meant for reflection turns into a deadly investigation at sea.

Aboard the Majestic, a grand 19th-century ocean liner travelling from Greece to Constantinople, Matthew Fairchild is hoping for quiet time to grieve a lost friend and find some sense of direction. Accompanied by his loyal dog, Oscar Wilde, he intends to spend the voyage in peace before reuniting with friends at the London Institute.

That plan is disrupted when a murder takes place on board. Tension rises as suspicion spreads through the ship, and the presence of a vampire Downworlder adds to the growing danger. What was meant to be a journey of healing quickly becomes something far more sinister.

Forced into action, Matthew finds himself drawn into an investigation where nothing is as it seems. He is joined by Sylvain Verlac, a Parisian Shadowhunter carrying his own hidden grief. Together, they must navigate shifting alliances, buried secrets, and rising fear among the passengers.

As the ship continues its voyage, the stakes grow higher. With danger closing in and time running out, Matthew must uncover the truth before the killer strikes again.

Blending mystery, supernatural tension, and emotional depth, this novella explores grief, identity, and the search for purpose in the midst of chaos.
