The Catafal's Crow. Of Fear and Flowers, #1

Leira Auberon has always been ridiculed for her lack of fear and the blood-colored birthmark that covers much of her face. After being blamed for a village death, Leira's only chance of escape is to join the crew of the catafal-the ship that collects the Kingdom of Agrestis's dead. Most people fear the catafal and what it stands for. But Leira has never felt fear, and she is intrigued by the ship's menacing captain.
Leira soon learns to love life at sea. But when a group of immortality-seekers attack the catafal, its misfit crew are drawn into a rebellion threatening the kingdom's peace. Leira is ready and willing to defend her home aboard the ship. But when her reality is twisted in surprising ways, she finds herself facing the one thing she never expected.
