Once upon a time, a young girl cried all her sadness into the lake of her local city park, and a lonely black swan drank a tear and was transformed...

For Signet, being human is much harder than she imagined. There are machines that are trying to kill her, people who want to replace her, and dizzying new emotions she'd rather not feel. When she finds herself torn between two wildly different worlds, she must discover how much she's willing to sacrifice, where she really belongs, and who she truly is.

Enter a world where birds shapeshift into wizards, women emerge from sealskins, swans transform into maidens, and love is the most powerful enchantment of all.
