Bluestar's Prophecy  

In the prologue, the Dog Pack incident from A Dangerous Path is shown in Bluestar's point of view.

 A ThunderClan patrol finds squirrel blood and WindClan scent on their side of the border. They come back and complain to Pinestar, who listens to what they've found. Although WindClan scent was everywhere, no bushes were marked, and the scent might have just drifted down. A few warriors argue that squirrel blood and Clan-scent aren't a coincidence. Pinestar still refuses to battle on account of there being not enough evidence. Goosefeather, the ThunderClan medicine cat, later receives a sign from StarClan telling them to attack WindClan. He says that they will be crushed by WindClan. The prey-stealing was just the beginning, and soon, WindClan would destroy them, tear down their camp, and ThunderClan territory would be a wasteland. Many warriors are immediately ready to attack WindClan first, as they have the advantage and must use it. Pinestar isn't sure, as there are cold moons ahead and kits and queens to be protected. Senior warriors gather around him, pelting him with arguments, and Pinestar makes the decision to battle at dawn. On the day of the battle, the clouds threaten to drop their load, and some cats mutter that the conditions aren't right for battle. Featherwhisker gives them herbs for battle that will give them strength. Goosefeather then gets another omen in a piece of catmint clinging to the vole's other flank, telling him to take the battle into WindClan's camp and to destroy their medicine supplies. Many cats protest, as destroying their medicine supply would be to attack the innocents as well. However, Adderfang says that they shouldn't want to save their elders and kits instead of ThunderClan's. Many cats continue to have doubts in believing that the sign was true. They lead warriors to the heart of the camp, and start to attack. A few warriors get to the medicine den, destroying the supplies. Hawkheart tears after them, and manages to kill Moonflower. At this point, Pinestar calls for ThunderClan to retreat, and Heatherstar faces him, saying the attack was unjust and that StarClan would have never let them win. Pinestar takes his wounded and leaves. They do as they were told, but many cats don't believe the sign was true. Leopardpaw has a bad claw injury and Stonepelt's injuries never heal, so he retires to the elders' den. When the defeated warriors return to camp, Swiftbreeze attacks Goosefeather, but Adderfang and Tawnyspots stop her before she leaves a claw mark. While Bluepaw helps Lionpaw and Goldenpaw, Lionpaw is convinced that in a battle, there is no time to think. Swiftbreeze corrects him, saying that in a battle, planning is the most important weapon you have.

After this session, RiverClan crosses the ice, trying to take Sunningrocks back. Pinestar calls for a patrol to be made to attack from the far side. After this, a second wave will finish them off. He leads the first patrol, and Hailstar calls that an ancient wrong has been set right. Pinestar starts to attack, but RiverClan has the upper hand. Suddenly, Stormtail leads the second patrol, and the possession of the upper hand changes. Hailstar orders to retreat, and the warriors scramble across the ice, shattering it with their hind legs so ThunderClan couldn't follow. 

RiverClan re-sets the scent markers, and Pinestar refuses to fight. Lionpaw wants to fight in a battle, but Bluefur reminds him that a battle's not fun. Later, RiverClan mocks ThunderClan as they set foot onto Sunningrocks. Lionpaw calls them cowards, and Swiftbreeze pulls him back, saying a smart warrior only starts battles he can win. Hailstar now wants more land, and he sends a patrol of cats to set markers in a forest portion of ThunderClan's territory. A ThunderClan patrol finds them, but being skilled in stalking through undergrowth, they get back and tell Sunfall as Pinestar is missing. Swiftbreeze observes that they don't know where to head, and Sunfall concludes that they're looking for a patrol to attack. ThunderClan makes plans, such as fighting them where the undergrowth is thickest, as RiverClan isn't used to fighting in brambles. They split into three patrols and plan to attack on three flanks. ThunderClan attacks, and they immediately start to win. They corner the RiverClan warriors, and soon outnumber fit warriors. Shellheart calls the retreat, and ThunderClan maintains their portion of the forest.

 When Bluefur takes Snowfur out, they encounter three ShadowClan warriors they had crossed the border to chase a squirrel. They jump out at them, and the ShadowClan warriors think that since there's three against two, they might as well take the squirrel and go home. However, Snowfur jumps out at them and Bluefur helps. The cats are terrified, and hastily cross the Thunderpath to go back to ShadowClan territory. During this, Snowfur tries to cross after them but gets hit by a monster. 

When Sunstar offers Bluefur the choice of being deputy, Bluefur notes that Sunstar has lost three lives in battle in order to make ThunderClan strong and feared.
