Lightlark (Lightlark, 1)

Welcome to the Centennial. Every 100 years, the island of Lightlark appears to host the Centennial, a deadly game that only the rulers of six realms are invited to play. The invitation is a summons – and a chance to finally break the centuries-old curses that plague each realm. But the price of losing is death. Isla Crown is the young, secret-keeping ruler of Wildling – a realm of temptresses cursed to kill anyone they fall in love with. To break her people's curse, Isla must lie, manipulate, and forge alliances with dangerous rivals, all while a series of murders threatens every ruler on the island. As the game turns deadlier and her secrets grow harder to keep, Isla discovers that nothing on Lightlark is what it seems – and that love itself may be the most dangerous game of all.
