Ancient grievances, long-held grudges, and dangerous magic combine in this sweeping standalone fantasy perfect for fans of Tamora Pierce and Rachel Hartman.

They came in the night as she dreamt, in her berth, on a ship sailing home to del Mar. After, they would be all Reyna thought about: two carracks painted scorpion black. No emblem on either forecastle, no pennants flying above the mainmasts to hint at a kingdom of origin.

Never a good sign.

As the granddaughter of a famed navigator, seventeen-year-old Reyna has always lived life on her own terms, despite those who say a girl could never be an explorer for the royal house of St. John del Mar. She is determined to prove them wrong, and as she returns home after a year-long expedition, she knows her dream is within reach. No longer an apprentice, instead: Reyna, Master Explorer.

But when menacing raiders attack her ship, those dreams are pushed aside. Reyna's escape is both desperate and dangerous, and when next she sees her ship, a mystery rises from the deep. The sailors--her captain, her countrymen--have vanished. To find them, Reyna must use every resource at her disposal . . . including placing her trust in a handsome prince from a rival kingdom.

Together they uncover a disturbing truth. The attack was no isolated incident. Troubling signs point to a shadowy kingdom in the north, and for once, the rulers of the Sea of Magdalen agree: something must be done. But can Reyna be brave enough to find a way?
