Synopsis from Goodreads

London, 2218 A.D. Seventeen-year-old Zee is an intern empath. She’s focused on her job, poised for a great career—until one day an attractive patient undoes her hard-earned calm. As an empath, she cannot afford such distractions, but neither can she stay away from David, even when she discovers he’s one of a mysterious alien race. As London comes under attack by anarchist bombings, and as Zee struggles to get a handle on her unusually strong psychic abilities, David starts pulling away. Although Zee’s sure he’s attracted to her, David has secrets he cannot share. But it’s too late for Zee. She’s losing her heart to the gray-eyed alien boy, and she’s determined to follow him—no matter how far it may take her.
