Capture the Flag (Star Trek: The Next Generation - Starfleet Academy #4) by John Vornholt

It's Geordi La Forge's first year at Starfleet Academy TM, and it isn't going well. He's been all over the galaxy with his Starfleet officer parents, and his blindness has not been a handicap, thanks to his VISOR. But somehow he's always picked last for competitive teams, and deep down he wants to be just like all the other confident students. When he defeats the top-ranked team in an elimination game, Geordi wins the respect of his classmates, and the hatred of the other team's captain, Jack Pettey. Pettey threatens revenge, and his opportunity arrives with training exercises on the planet Saffair. Geordi's team faces Pettey's, and without supervision on the uninhabited world Pettey will stop at nothing to win.
