It's a Zoo in Here — James Patterson; Brian Sitts

Rafe feels like a caged lion at his summer job at the zoo--until a real lion desperately needs his help.

Rafe Khatchadorian is days away from sweet, sweet summer freedom until bad grades threaten to land him in … SUMMER SCHOOL.

It's impossible to fail out of a summer job, right? Wrong. He strikes out at the zoo then grosses out at a billionaire's country club:

Digging a pit for the annual clambake
Scrubbing chewed bubblegum, sooty fireplaces, and . . . toilets
Polishing the chrome on his boss's ATV

Rafe is destined for the Failed Jobs Hall of Fame until an encounter with an endangered lion puts his wildlife knowledge to the test… and it's more than his grade on the line this time.
