Happiness for Humans is a warm-hearted, joyful story about being just a little bit different, perfect for readers who loved The Rosie Project and Eleanor Oliphant is Completely Fine. I am by no means alone in thinking that this funny, madcap romp for the digital-age, featuring believably flawed characters (not all human), deserves to be a hit. Rights have been sold in 26 territories and Working Title and Fox 2000 have a Film option on what could be Sleepless in Seattle meets The Lobster. One of the factors in its favour is that, like David Nicholls' One Day or Graeme Simsion's The Rosie Project, it should appeal to male and female readers.
