Beneath these Cursed Stars by Lexi Ryan

Welcome to the world of Faerie, where the action is fast-paced, characters leap off the page, and romances are SWOON worthy (be warned, you will want the second book on hand as soon as you finish the first, otherwise you’ll be dying on the edge of that cliffhanger)! Told in dual-POV, Princess Jasalyn is determined to end an evil king’s resurrection and shape-shifter Felicity is determined to avoid the prophecy foretelling her father’s death by her own hand. The solution? Obviously, Felicity shape-shifts to take Jas’s place, allowing her to hunt in peace, but as the human and fae realms’ fates hang in the balance, the girls realize their missions may be at risk… as well as their hearts.
