One girl determined to heal her sister and another looking for purpose in a nation on the brink of war. And unicorns—with a twist you’ve never seen before.

It's Rowan Tritonia's sixteenth Naming Anniversary. Her plans for the day never included a headache that causes her to almost faint on a day meant for celebration. When the world comes back into focus, her brown eyes have changed to magenta. But what scares her more is that everything around her is now black and white coupled with a mysterious ability to see the light and shadows in a person's soul. Then a local cleric implies that Rowan could have the power of Sight, a gift which has only been seen in the stories of unicorns in the Book of Verimor, an ancient text. Rowan is perplexed. Why would Verimor give her something she never asked for instead of answering her greatest prayer to help her younger sister, Blythe?

News of the girl with Sight quickly travels beyond Rowan's local village. When the King of Wisteria learns of her gift from a letter, he summons her to the castle. With growing political tensions from neighboring nations, Rowan may be able to provide the aid they desperately need. Linnea, the king's sister and his primary advisor, prays that Rowan has truly been blessed by a unicorn and can save the nation and its people from encroaching darkness.

Meanwhile, back at home, Blythe, sets out on her own journey. She feels helpless, tied down by the pain that keeps her homebound most of the time. Although she wears a smile to comfort those around her—especially her family—Blythe wonders if her life will ever amount to anything more than fading into the background. Is she truly too broken for any greater purpose, or can Verimor still use her?
