The Mystery

When an old man in an even older house dies mysteriously, twins Jack and Jaide Shield find themselves drawn into a dangerous treasure hunt in some deep, dark places. Jack and Jaide are troubletwisters-gifted with magic and cursed by The Evil, a force that will stop at nothing to destroy their world. The old house holds something very important to The Evil-and Jack and Jaide must race to find it, even though they don't know what it looks like or where it is.

Jack and Jaide aren't the only one...
