One of its legs whipped out and grabbed Callum by the ankle before he could take another step backward. He fell to the floor and took me down with him.
Hot fury shot through my veins. I jumped to my feet, uprooted a cardboard M&M's display, and hurled it at the giant spider.
It knocked the display away with another leg. Callum crawled to his feet and lunged to my side, his breath coming in short bursts.
"What do you want with me?" I shouted.
"Your gift of blood led One and Two straight to your house," the spider said in a rough voice. "They weren't sure who was more powerful, you or your sister. So they tested your strength by pretending to choose your sister."
Questions rose in my mouth like bile. This was a game. Always had been. A game played by cheaters, and I'd joined in completely unaware of the rules.
