Seraphina once believed she was the vampire prince Alistair's one true love. Five years ago, he rescued her and declared her his soulmate. But when she was attacked by werewolves while pregnant, he sent all the healers to her stepsister Isabella, who had forged a "life bond" with him, causing her to miscarry. Over five years, he favored Isabella—stealing Seraphina's paintings, giving her the studio key, and planting flowers that Seraphina was allergic to.

After the truth came out, she faked her death and escaped under the alias Phoebe Miller. She later became an art restorer, was discovered by gallery owner Julian, and rebuilt her life independently. Isabella died in prison, and Alistair, consumed by regret, became an arbiter. A year later, her Light and Shadow series succeeded, and holding Julian's hand, she finally found a peaceful life.
