The Love Theorem by Camilla Isley

Lana loves four things: science, her cats, her friends, and her books. She's on her way to earning her professorship when she finds out her long-term boyfriend has been sleeping with her best friend! That discovery has her hiding in the broom closet at a posh hotel. Only, it turns out broom closets are the place to be these days. Christian Slade, America's sexiest man alive (as voted by fans), in a desperate attempt to escape the paparazzi finds himself in a broom closet with one sobbing occupant. Unable to leave a damsel in distress, he offers help, only to realise she has no idea who he is! It's like he's been given a gift. A smart, beautiful woman, who isn't after him for fame and fortune... Soon Christian is buying a Tesla to impress his scientist with his eco credentials and taking her on dates where no one will recognise him. But as Christian falls in love he worries what will happen when Lana finds out who he is?
