Sophie: Liam is Formula 1's golden boy – though he's nothing but a fraud. Charming, devious, seductive… and someone who promises to fulfil all my naughty bucket list items.

I force him behind the safe lines of the friend zone, but instead of accepting our friendship, he strikes a deal: one season, one list, one dirty secret.

Liam: Sophie is my greatest fantasy brought to life – and a major threat to my contract renewal. She's a part of the rival team and someone I should resist at all costs. Everyone is against our friendship: my boss, her dad… me. Yet I'm captivated by her and the naughty list she created.

Screw platonic, I want catastrophic.
