Coco Banjo has been unfriended by N. J. Gemmell

Coco Banjo series. Penguin, 2015. ISBN 9780857987358
(Age: 7+) Recommended. School. Friendship. Bullying. Canberra. Coco is thrilled to be going on an excursion to Canberra with her best friend and the rest of her class. But Coco is blamed by her teacher for a series of incidents on the trip, making her friend unfriend her. The cool group on the bus trip claim her friend and Coco is devastated. She must do something to overcome the bullies and get back her friend.
At time Coco is a little too good to be true, trying to think only the best of people, but common sense takes hold and she is able to show the bullies up for what they really are.
In between times, the book deals with nits, a hidden pet rat, the Prime Minister and a touch of feminism. And a tour around Canberra is an added bonus. All in all an easy but entertaining read for mid to upper primary girls. This is the second book in the series.
