Belly Up

by Gibbs, Stuart

When Henry the hippo turns up dead at FunJungle, the zoo's newest and most expensive attraction, everyone assumes it was just a tragic accident. Everyone, that is, except twelve-year-old Teddy Fitzroy. Living on-site as the son of two staff members, Teddy knows the facility better than anyone and quickly realizes the official story does not add up. What follows is a sharp, fast-moving investigation that pits a kid with a keen eye for detail against a corporate machine determined to keep the truth buried. The book balances genuine suspense with a dry, observational humor that keeps the pages turning. If you enjoy stories about underdogs who refuse to be silenced by self-important adults, or if you simply love a well-plotted mystery set in a world that feels both expansive and claustrophobic, this will hit the spot.
