I love you... but what if I can't love your life?

Ava is sick of online dating. She's always trusted her own instincts over an algorithm, anyway, and she wants a break from it all. So when she signs up to a semi-silent, anonymous writing retreat in glorious Italy, love is the last thing on her mind.
Until she meets a handsome stranger... All she knows is that he's funny, he's kind and - she soon learns - he's great in bed. He's equally smitten, and after a whirlwind, intoxicating affair, they pledge their love without even knowing each other's real names.
But when they return home, reality hits. They're both driven mad by each other's weird quirks and annoying habits, from his eccentric, naked-sauna-loving family to her terribly behaved, shirt-shredding dog. As disaster follows disaster, it seems that while they love each other, they just can't love each other's lives. Can they overcome their differences to find one life, together?
