Zoobreak by Gordan Korman
This book is a about griffin 'the man with the plan''s friend savanna has her capuchin monkey Cleo stolen from her but when their homeroom class takes a fieldtrip to a zoo/boat hybrid Cleo is found aboard as the man of the plan griffin formulates a plan named zoo break. when their plan succeeds the take the other malnourished animals on savanna's whim and distributed them among their team. on the account that savanna's friend from the zoo is elsewhere, wherein griffin formulates zoo break II, to sneak in the animals into the state zoo.
In my opinion it's a good book it just needs more related to the story details the part where they follow through with the plan are kind of short.
Realistic yes but not to not to much realism but here was bits and pieces that were unrealistic like owning a capuchin monkey , Griffins hacker sister mellissa , the parts that can happen like Ben's narcolepsy and mr nastase personality that one is very common.
The book's main audience is direct towards sixth and seventh graders mostly for the reason it's in large lettering it also makes it easer to read for the visually impaired.
