"Rhett and his brother, Nash, have never been allowed to play board games. It's their mom's most important rule; the twins don't know why, but they know not to push her on it. When their mom suddenly disappears, they're reunited with Ace, their long-lost grandfather, who reveals that their family is descended from a board game character who escaped his game and lived in the real world. Their family now has the ability to enter the world of any game they want--but this gift also comes with a price. A game character who’s wanted revenge against their mom for decades has finally caught her and is holding her hostage in the world of a game. Which game? That’s up to Rhett and Nash to figure out, even if it means breaking Mom’s most important rule. But as they learn to use their newly discovered ability, exploring new worlds and facing new challenges and risks, the brothers quickly realize that saving Mom won't be all fun and games"--Provided by publisher.
