Hostile Ground (Stargate SG-1 #25)

It was meant to be an easy mission, a walk in the park. But SG-1's first trip off-world after Colonel O'Neill's return from Edora (STARGATE SG-1: One Hundred Days) proves to be anything but easy.

Tapped for a covert assignment, O’Neill must conceal the truth from his team at all costs. So when Dr Daniel Jackson is injured and the mission begins to go awry, tensions quickly reach breaking point. Stranded on a hostile planet, and desperate to find a way home before it's too late, O'Neill leads his fractured team on a desperate journey across a barren and forsaken world.

Faced with an enemy more vicious than anything they've encountered before, only SG-1's strength as a unit will keep them alive - if the secret O'Neill is hiding doesn't tear them apart first...
