Hidden behind the clouds, giant dragons guard the most powerful magic in the world from prying eyes. On one magical night, once every ten years, these leviathans reveal themselves to a fanfare of costumes, music, and parades in the Chimera Carnival! But this time, something's wrong. When Beetle, Penny, and Kat decide to check out the empty carnival site one night, they discover an injured dragon screaming for help. And the more Beetle uncovers about the Chimera Carnival, the more sinister it gets. Dragons who arrive for the early festivities disappear without a trace. Beetle's magic begins to go haywire. And Kat's parents come back to town, worrying both girls about whether they have a future together. And in the catacombs beneath the demolished 'Allowstown mall, something hungers for dragon magic. And Beetle and her friends are already more entwined with it than they could possibly imagine.
