““soon as they reached the first archway, the polecat Gale found them. She scurried up Hazel’s side and curled around her neck, chittering crossly as if to say: Where have you been? You’re late. “Not the farting weasel again,” Leo complained. “If that thing lets loose in close quarters like this, with my fire and all, we’re gonna explode.” Gale barked a polecat insult at Leo. Hazel hushed them both. She could sense the tunnel ahead, sloping gently down for about three hundred feet, then opening into a large chamber. In that chamber was a presence…cold, heavy, and powerful. Hazel hadn’t felt anything like it since the cave in Alaska where Gaea had forced her to resurrect Porphyrion the giant king. Hazel had thwarted Gaea’s plans that time, but she’d had to pull down the cavern, sacrificing her life and her mother’s. She wasn’t anxious to have a similar experience. “Leo, be ready,” she whispered. “We’re getting close.” “Close to what?” A woman’s voice echoed down the corridor: “Close to me.” A wave of nausea hit Hazel so hard her knees buckled. The whole world shifted. Her sense of direction, usually flawless underground, became completely unmoored. She and Leo didn’t seem to move, but suddenly they were three hundred feet down the corridor, at the entrance of the chamber. “Welcome,” said the woman’s voice. “I’ve looked forward to this.” Hazel’s””
