Swift: Volume 1

To save her people, a wingless girl must learn to fly. As a piskey girl born without wings and raised underground, Ivy yearns for flight almost as much as she misses her long-lost mother. But the world outside the Delve is full of danger, and her dreams seem hopeless until she meets a mysterious faery who makes her an enticing offer: If Ivy helps him escape the Delve's dungeon, he'll teach her how to fly.
