Going Rogue by Kass Barrow

He came to save mankind. Falling in love wasn’t part of the equation.
Blake Denby works as a receptionist at the Warren Hotel in London’s Bayswater. For the past four months he’s been working the zombie shift and it’s played havoc with his sex life. Living at the opposite end of the day to everyone else has made it virtually impossible to get a date.
When an enigmatic stranger turns up at the hotel, Blake is instantly smitten by the mysterious and stunningly attractive stranger. But behind those smouldering blue eyes, lies a dark secret. He’s not of this world. There wasn’t even a human heart beating in his chest until this morning.
His visit to Earth is fleeting. He must perform a vital task that will ensure man’s future and then leave. But there’s a problem. Subjected to the full gamut of human emotions, long-suppressed desires quickly bubble to the surface. The sort of desires that the stranger is ill-equipped to deal with.
He isn’t meant to fall in love.
Especially not with a human male.
As his and Blake’s lives become inexorably entangled, the stranger struggles to stay focused on his mission.
The fate of the human race rests on what he does next. Will he risk everything, even his own future, for the sake of love? And will Blake’s heart ever recover if the stranger returns home?
