Hye-Jynx:Quest One

Nine-year-old Neil never expects to have an adventure. He likes studying science from a safe distance – by himself, on his computer, in his room. Suddenly, he's not alone. Two tiny wizards, Hye and Jynx, pop out of his rubber plant and need his help. They don't have enough magic to get home and must travel to the natural wonders of the world to find more enchantment. They need Neil as an anchor when they travel in Magic-Time because his room is the only way back to their world. He reluctantly agrees to go with them. 
Their first quest is traveling to the Grand Canyon. Interrupted mid-spell by Neil's younger sister, all four arrive in the Grand Caymen Islands instead of the Grand Canyon, thousands of miles from their destination. He wonders if he and his sister are going to get back home.
