Description: 

Carissa Shae, the half-faerie apothecary from the island of Moss Hill, is setting sail to the legendary island of Hy Brasil. The whole of Moss Hill is counting on her to persuade the Tuatha de Danann to help them fight the unseelie, evil faeries threatening their shores. This ancient, powerful faerie race isn't likely to help, but when one of the passengers ends up dead, Carissa is more determined than ever. In her attempt to solve the onboard murder, Carissa might also solve a century-old mystery - one that could persuade the Tuatha de Danann to offer their assistance after all.
