When we get to the island

Hani is 12 and invisible, and yet everyone wants to capture him.

After escaping from Syria with his sister, he finds himself working in atrocious conditions somewhere in Scotland.

When his sister disappears, he begins a perilous journey to find her, across some of the wildest terrain in Scotland. Mia is also on the run, and sometimes it feels as if she will never stop running.

When she helps Hani escape from his captors, the two become inseparable.

Her dream is to reach the island where she was last happy, when her parents were alive, and find the little house she believes they still own.

Once we reach the island, she tells Hani, everything will be okay. But their journey takes them into dangerous landscapes, hunted by dangerous men, chased through a system of underground flooded caverns while a great storm sweeps the coast.

Whatever happens, Mia knows that she must help Hani to find his sister.

What they will really find at the end of their journey may come as a surprise to both of them. Alex Nye is the award-winning author of Chill and Darker Ends.
