Sixteen-year-old twins Axel and Nate Hartz know their rhythm in the quiet coastal town they call home – surf, school, mates, repeat. But when strange things begin twisting the edges of their everyday life, cracks spread through a world that once felt safe and predictable.

Nate’s nightmares echo into daylight, and the eyes he once sketched in the margins now seem to stare back at him from the dark. Axel’s body is straining under a pressure that feels like it wants to break him, making it harder for him to stay strong for everyone else.

They don’t talk about it. They don’t know how. They try to shake it off … but the whispers only grow louder, and the harder they fight them, the faster the changes close in.

When one terrifying night puts their friends in danger and tears open the boundary between normal and impossible, the brothers are forced to reckon with what’s been waiting inside them – and whatever moves in the shadows around their town is only just beginning.

Royal harpy Adora Heartstone has only ever known the broken realm left behind by the Shadow War. A century has passed since the curse stole her people’s wings and erased their males, shattering the harpy magik that sustains Octavia. The realm has never regained its full strength – and is slowly losing the power to hold back the ever-rising gloom.

Adora has felt the pull of her duty for as long as she can remember, so when she joins the Order of Octavia – the realm’s magikal alliance forged to stand against the gloom – she prays the training will finally make her worthy of the legacy she was born into. But as she learns more about the mortals of Earth, she realises just how vast her duty is – not only to Octavia, but to millions of lives who have no idea a threat is rising.

As revelations unravel the secrets of her origins and expose the ancient threat moving in the shadows, Adora learns the truth: what lives within her could save Octavia … or unleash the same devastation that destroyed it once before. And this time, the darkness won’t stop at Octavia – it will break through to Earth.
