The year is 2059. 15-year-old Noa Blake has to take an exam to stay in the Territory – but her childhood friend Jack has been sent to the disease-ridden Wetlands where few people survive long. Noa and new boyfriend Raf have vowed to rescue Jack, but how? Can they find a gap in the Territory’s defences and will they find Jack in the wilderness beyond? And how divided are Noa’s loyalties when put to the test.
