But each world is more treacherous than the last, and staying alive for even a day will be the ultimate test of their wits, courage, and determination. And when they finally puzzle out what is happening to them and why, the impossible happens: things get even worse. Because far more is at stake than just their lives. And the odds against them could not be any greater . . . Out of This World is a fast-paced adventure sure to delight young and old alike, packed with breakneck action, brilliant escapes, thrilling cliffhangers, and plenty of heart.
