Once he accomplishes this, he'll be a full general of GreenClan, right hand to Viperstar, with all the power he's ever wanted. But a blast from the past gives an unexpected twist to his plans, and makes him question who he really is.
Tornadoheart has rejoined the rebellion, but that doesn't mean their problems are over. The secret patrol is faced with a tough decision when the reach the River of Stars once again, and meanwhile, back in the Tunnels, the cats realize someone has discovered their hiding place.

After a daring, quickly-put-together rescue mission to help the secret patrol, the four best friends are finally reunited. Now, as they make their way back to the Tunnels, they must decide on some important issues concerning who they are as the Hidden, and what they do.
As they prepare for Aquatail's attack, the cats encounter a group of mysterious travelers. When they realize that these cats are part of the Network, it seems like a wonderful revelation. But Viperstar is clever beyond their wildest dreams, and they just might be walking into a trap they will never walk out of.
It's time for the Hidden to face down a long-time foe. As Aquatail tries to invade the Tunnels, they put up a brave stand, knowing that to let the she-cat in will be disaster. They need to hold her off, or die trying.
How much is too much to give for freedom? And how far should you go to save a friend's life? With Strongheart on the verge of death, Finchnose, Silverbreeze, and Reedfur must answer those questions quickly.
Not that they're complaining, but the Hidden cats are wondering who exactly was it that saved Strongheart the night of the battle? When the answer steps forward, they realize that even though they're facing all of GreenClan and possibly the biggest war they've ever seen... there could still be hope. There are still others on their side.
