Sephy and Callum have been friends since early childhood. And that's as far as it can go. Because theirs is a world full prejudice, racism, distrust and mounting terrorist violence.

Despite all this, a romance builds between the two friends. But this is a love story that could lead both of them into terrible danger . . .
