Finalist for Mark Twain rather than Somerset

I've just had word that In Search of the Magic Theater has been moved from competition for the Somerset prize (literary/contemporary) to the sibling Mark Twain prize (satire/humor), and it is a finalist for Mark Twain. I know there are some moments in it that make me laugh, but compared to some novels I've written, it's fairly serious! Readers, what do you think? Is this an unusually funny or satirical novel?
