It’s a still, hot summer in Perth, only heat shimmying off the city’s glass buildings, and not much to do but surrender to the cool of Beatty Park pools. The locals are out in full force: teenagers flirting, even the ragtag kids from the refuge.

But something is moving under all the stillness; something dark and untamed. It’s moving through lives and connecting them with its sonar trembles: Auntie, in town with Jerome to find his mum, who has run away; Kevin, tired of his lot, dealing with raucous kids and bottlenecks and a city that seems to be growing hostile; Karri and his other-worldly sister Bat Girl; Jackie and her sisters, sharing smokes by the pool.

In this exquisite, lyrical verse novel from acclaimed playwright Christine Evans, we are invited to witness the strange and invisible ways people are drawn together and pulled apart-and to venture to the ultimate catastrophic release that might ultimately return them home.
