The Terrible Two (book series)

The Terrible Two is a series of four novels aimed at tweeners. The two protagonists are Miles Murphy and Niles Sparks, who are in the same grade at the Yawnee Valley Science and Letters Academy. It is the local public school in Yawnee Valley, a town in a country area where the main industry appears to be dairy cattle. Originally rivals, Miles and Niles discover that they have a shared love of pranking, and begin to institute elaborate pranks, often aimed at the principal of the Yawnee Valley Science and Letters Academy, Barry Barkin.

The series was written by Jory John and Mac Barnett, illustrated by Kevin Cornell, and published by Harry N. Abrams. The four books in the series are: The Terrible Two (2015), The Terrible Two Get Worse (2016), The Terrible Two Go Wild (2018), and The Terrible Two's Last Laugh (2018).

The Terrible Two
The Terrible Two is a book in the series. It introduces Miles Murphy, who has recently moved to Yawnee Valley with his mother. Miles is upset about the move, away from his former town and school where he had established his reputation as a prankster. On his first day of school, he meets Niles Sparks, an extremely well-behaved student who has earned the title of "school helper" from Principal Barkin. Barkin is the victim of an elaborate prank the first day of school and blames Miles, without any proof. Miles gradually realises that behind the facade of good behaviour, Niles is a committed prankster. They eventually team up, with Niles having considerable planning abilities, and Miles having a strong skill at improvisation, when a prank looks like it may be about to be detected. The book finishes with an elaborate prank on Principal Barkin, and his son, Josh Barkin.

Josh is the school bully and class president. He is opposed by Holly, a bright student who regularly runs in opposition to Josh for the class president. She is sceptical of Niles's excessively good behaviour, and befriends Miles, who is an outsider. She gradually realises that Miles and Niles have become friends and is somewhat puzzled, as Niles and Miles seem completely different in attitudes.
