A mother's love can be deafening . . .

Isaac is Hannah’s entire world. She knows that her son is gifted, and that those gifts make him vulnerable. To keep him safe, she spends every waking moment by his side. If she lets her guard down, lets him out of her sight, lets him show what he’s capable of, he will be taken from her.

When the Soundfield arrived twenty years ago, the world changed with it. Now, people are forced to live at night due to the deadly heat of the day, food and water are scarce, and everyday life is punctuated by the constant and disconcerting hum from the Field. A brilliant scientist, Hannah spent her early career working on the enigma of the Soundfield, looking for answers; now, resigned, she has focussed all her energies on keeping Isaac living, not just alive.

To do so, she will have to lie to the people she knows and hope she can trust the ones she doesn't. Because the only thing more dangerous than her lies, is the truth of what she has done.
