Maas and Emily R. King, this first book in a dark and action-packed new series is impossible to put down! Light magic is forbidden.  Dark magic spells death.  Haven has both. ​ After the Prince of Penryth saved her from captivity, seventeen-year-old Haven Ashwood spends her days protecting the kind prince and her nights secretly fighting the monsters outside the castle walls.  When one of those monsters kidnaps Prince Bell, Haven must ally with Archeron Halfbane and his band of immortals to rescue her friend.  Her quest takes her deep into the domain of a warped and vicious queen where the rules are simple: break her curse or die. Lost in a land of twisted magic and fabled creatures, Haven finds herself unprepared, not just for the feelings she develops for Archeron, but for the warring powers raging inside her.  Her rare and forbidden type of magic may be their only hope . . . but mixing light and dark comes with a steep price.  Haven’s soul. Faced with impossible love, heartbreaking betrayals, and a queen intent on destroying the realm, only one thing remains certain.  Haven must shatter the curse or it will devour everything she loves.  Welcome to the Kingdom of Runes where immortals and humans clash, light and dark magic reign, and mythical creatures lurk in the shadows. If you like fierce heroines, enemies-to-lovers romance, wild plot twists, and endearing characters that stay with you long after you reach the end, you need to discover the book readers are calling dark fantasy at its best. Just make sure to clear out some space on your calendar first! **Oath Taker was previously published in the boxed set Shattered Worlds under the name Curse Breaker. This is a revised second edition.

But they must learn quickly, for a nearby island has set its hungry eyes upon their home. When the invasion comes, the twins must don their wings and ready their blades to save those they love from annihilation.ShadowdanceA Dance of CloaksA Dance of BladesA Dance of MirrorsA Dance of ShadowsA Dance of GhostsA Dance of ChaosSeraphimSkybornFirebornShadowborn
