Wendy Mass: Robin Hood, The One Who Looked Good in Green

Robin has a bad habit of getting into trouble, and a better habit of getting out of it (barely). He lives on an isolated outpost in the middle of nowhere and has no idea why his parents disappeared years ago. Then a strange delivery arrives at his doorstep, and the past is suddenly very present. Marian was raised to be a very powerless girl in a very powerful family. But that hasn't stopped her from making her own adventures and trespassing in some places her parents definitely don't want her to see. She has no idea what life would be like outside of her home, until a mysterious invitation forces her to leave everything behind. Robin and Marian have lived very different lives in very different places. Their paths should never, ever cross, but before they know it, they are thrown together on a quest that requires legendary bravery, quick-witted escapes, and the ability to get along with each other. The sky's no longer the limit on what Robin and Marian can do, as long as they manage to do it together.
