“A movement in Hotel Valhalla’s garden caught my eye. I looked closer. And immediately wished I hadn’t. Legs spraddled and wearing nothing but a pair of leather short-shorts, Thor was bending, twisting, and squat-farting. Strapped to his ankle was a device shaped like a valknut, a design of three interlocking triangles. “What in the name of me is my son doing?” I asked in bewilderment. “Who, Thor?” Heimdall looked over his shoulder. “He’s warming up for a jog through the Nine Worlds.” “A jog. Through the Nine Worlds,” I repeated. “Yep. If he logs ten million steps on his FitnessKnut—that thing around his ankle—he earns a cameo appearance on a Midgard television show. That’s why I had his goats. He said they’d slow him down.” “That’s ridiculous!” “Not really. Those goats aren’t exactly speedy. Unless they’re plummeting, that is.” “Not what I meant. . . . Never mind.” I cupped my hands around my mouth. “Thor! Thor!” Heimdall tapped his ears. “He’s listening to rock.” “Rock ’n’ roll?” “No, just rock. Boulders, gravel, stones.” ThorOdinHeimdallA JogThe Nine Worlds Author:Rick Riordan
