Hannah Martin is in sixth grade, has a mind of her own and an overactive imagination. Four amazing angels have chosen her to go on special missions for them, and when least expected Hannah is whisked away to incredible places all over the world. The angels send her clues so she can figure out what to do, but sometimes the messages aren't clear and her missions can get mixed up and even a little scary. But Hannah's adventures are fun and she gets to help other kids like herself.
On her first mission, the angels send Hannah to Australia, where she helps her new friend, Ian, track down some really mean poachers. The trouble is, they're not always sure who's getting hunted - the animals or them!
