Summary
Grace is a borrower, a tiny person living in the walls of a human university. He is also the worst borrower in history: reckless, curious, and absolutely incapable of staying hidden. When a hawk attack leaves him bleeding in a fox's den, he expects to die. Instead, he wakes up in the hands of a human. A human who bandages his wounds. A human who lets him stay. A human who makes him feel something he has never felt before.
Simon has spent his life caring for animals. He has never found a tiny person in his fox enclosure before. He has also never felt a magical bond snap into place just by touching someone. But there is something about Grace. Something that makes him want to keep him safe. Something that makes him want to keep him close.
A story about found family, impossible love, and the strange magic that happens when two people are exactly the right size for each other.
