This is the third book in the series by Joanne Macgregor, but can also be read as a stand-alone. Both Turtle Walk (2011) and Rock Steady (2013) were best sellers.
The eco-warriors are now in Grade 10 at Clifford House boarding school but this year, cracks are beginning to appear in their friendships, romances and their belief in themselves. When Samantha Steadman joins ecological activists to block fracking in the Karoo, she expects that her best friends will be right alongside her in the fight. But Nomusa takes a very different view of the controversial issue and Jessie, under the influence of a glamorous new girl at the school, is too obsessed with her weight and appearance to care about ecology.
Samantha feels very alone as she tries to deal with pressure from boys, school and her Poison Dwarf of a science teacher, all while uncovering a personal mystery from the past and struggling to save the Karoo as well as her friendships from splitting down their fault lines.”
