Inside London's first romance-only bookshop, Sarah Maxwell stands in the "smut hut" – a section dedicated to her store's more erotic titles.
Surrounded by shelves stacked with brightly coloured paperbacks – with titles including Just For the Summer, Swept Away and The Friendship Fling – young women are milling around, chatting and flicking through books.
Sarah says she wants to challenge the critics of romance fiction - often men - who diminish what she describes as "really high-quality writing" by saying "it's just smut".
"A lot of these books have strong world-building, amazing character development and a really good plot," Sarah says.
A surge in romance and fantasy sales last year pushed UK fiction revenue above £1bn for the first time, according to a report released last week.
