Hugo is a young Sasquatch. Boone is a young boy. After an unlikely
encounter, they've become an even unlikelier pair of best friends. After
saving up his Monster Card wrappers, Hugo sends away for a special prize
in the mail--a Monster Detector! Using the watchlike device, Hugo
quickly spots a monster right in his own cavern. Spooked, but still
excited about his prize, Hugo heads to school and finds yet another
surprise--his friend Boone! Boone announces he wants to go to Sasquatch
school, but no human has ever gone before, and not everyone is as happy
about it as Hugo. Boone's first day of school gets off to a rocky start,
but Hugo doesn't have much time to worry before he makes another monster
sighting and takes off after the creature. What follows are even more
surprises, ones that have Hugo rethinking what it really means to be a
"monster."
