The golden boy of Formula 1 has one goal in mind: become a four-time world champion. Guarded, distant, and calm, Miles Huxley is determined to break a record and refuses to let anything or anyone distract him. Unfortunately for Miles, he quickly learns that his focus will waver whenever he's around Indigo Bailey, his new roommate and his best friend's sister. Vowing not to let their blazing past affect their situation, he can't seem to forget about their shared nights and secret meetings. As the tension between them simmers, he realises that Indy is much more than a forbidden temptation—she's everything he's been trying to push away. Drawing a line seems to be the only solution to keep his control from breaking. As she starts a new job as a lead presenter in F1, Indy is intent on forging her place in a male-dominated world and having Miles open up to her. When Miles understands that Indy doesn't care about the line between them, his control loosens and speeds into overdrive. Will they be able to focus on their dreams without letting the sparkling embers turn into flames?
