Stargate Atlantis: Death Game

Colonel John Sheppard wakes up on an alien world, in the wreckage of a Puddle Jumper - and can't remember how he got there. As he puts the pieces together, he discovers that his team is scattered across a tropical archipelago, unable to communicate with each other or return to the Stargate. Prisoners of the local population, Sheppard and Teyla are taken as tribute to the planet's Wraith overlord, while McKay, Ronon, and Zelenka team up to mount a daring rescue.
