The Guardian

Aiden and Alistair Lorusso thought they were normal everyday fifteen-year-old twins that don’t get along like any other pair of siblings. They are as different as night and day. One brother is smart and handsome and the other is conniving and sinister. Their conflicts crescendo until one day, one brother disappears into another world through a secret portal and one brother has to stay behind to think of a plan to rescue him. Then they discover that they are right in the middle of a two hundred-year-old prophecy to save not only their world, but a whole other dimension! Now they are stuck together for good until they figure out how to be heroes.
