Plot

Twelve-year-old Kyle Keeley loves games of all kinds, especially the board games and video games created by beloved game maker, Luigi Lemoncello. The morning after getting grounded for breaking a window while playing one of Lemoncello's games, Kyle's friend Akimi Hughes tells him of an essay for a school contest; the winners will be the first to visit the new, grand library in Kyle's town of Alexandriaville, Ohio. Initially, Kyle wasn't interested in books, but when he realizes the new library will offer games and computers, he quickly makes a very brief attempt.

At school, Kyle discovers that Mr. Lemoncello designed and funded the new library, and that he plans to judge the essay contest. Mr. Lemoncello credits much of his success to the help of Alexandriaville's old public library in his childhood. Regretful that he missed out on a great opportunity, Kyle tries to hand in a much stronger essay late, but his teacher refuses to accept it. Undeterred, Kyle finds an email address for Mr. Lemoncello and sends the essay directly to him. When Mr. Lemoncello arrives at Kyle's school to announce the essay contest winners, Dr. Yanina Zinchenko, world-famous librarian, explains that they will experience the grand new library in an overnight visit. Then Mr. Lemoncello walks onto the stage and announces the winners: Kyle, Akimi, helpful Miguel Fernandez, nerd Andrew Peckleman, Bridgette Wadge, bookworm Sierra Russell, Yasmeen Smith-Snyder, Sean Keegan, popular girl Haley Daley, Rose Vermette, over-eager Kayla Corson and bully Charles Chiltington. 

That night, the children enter the library. They play a trivia game with the prize of sleeping in the library's opulent bedroom suite, which Charles wins, and they compete to find dessert for the prize of early entry to the Electronic Learning Center. Kyle and Akimi pair up to win that. Other activities that night include watching an IMAX movie and seeing animatronic presidential debate.

The next morning, Mr. Lemoncello announces a new game: the first to escape the library within twenty-four hours will win the chance to appear in Lemoncello game commercials and earn money as the company spokesperson. Sean, Kayla, and Rose choose not to stay, and Bridgette and Yasmeen are eliminated early, Kyle, Akimi and Sierra form a team. Meanwhile, Charles focuses on the fake book covers in the "Staff Picks" display case in the library entryway and soon begins to find rebus clues in the hard copies of those titles. Kyle guesses that the different books pictured on the backs of their new library cards are a clue; his team pursues those. Soon Miguel joins Kyle's team, and Charles forces Haley and Andrew into joining forces with him.

By late that night, despite Charles's insistence that he will win, he is concerned that Kyle's team is doing well. So, he convinces Andrew to steal Sierra's library card to gain access to the private meeting room where Team Kyle's collected clues and hints are displayed. Andrew is caught in the morning and ejected from the game. Haley decides to change sides. After several more games, Charles attempts to strongarm the last clue from Kyle in a physical confrontation. Charles is caught and removed from the game. Kyle and his friends decipher the last of the clues and escape the library just in time..
