This is the 1st book in a wonderful series. Tons of kids get mysterious envelopes with puzzles inside them. Each letter is signed by M. G. Nobody knows who this man is.
He sends the kids 12 letters and says if they ever want to stop the challenge, just burn the first clue. They all lead up to the magic words and the date they need to say them and the time and what they need to hit the ground with. Only three kids make it to that special day and they get winked away to M. G.’s headquarters. Master George, M.G., sends them to a different reality, and alternate version of our own world, reality prime.
There has been mutated powers in the 13th reality and they are sent there to take the makers barrier wand, the tool that allows you to wink between realities. They take it and are winked back to the headquarters.
I recommend this book to kids who like to solve mysteries and puzzles and enjoy fiction novels.
