It all started with a kiss... CALLUM SLADE had only known one thing: hockey. That's until he met her. Always in pink and spreading sunshine, Kate Blake brings all his walls down, just with a smile. Yet as much as he'd want her, he know he can't have her. She's his enemy's sister. His greatest temptation. Yet after a surprising first kiss, Callum knows there is no way he can walk away from her. No matter how hard chasing her could get. As the sister of their school's basketball captain, one thing has always been clear for KATE BLAKE: the other sports teams are off-limits. Yet after she finds herself kissing the hockey captain on the kiss cam, Kate starts rethinking that. Sure, Callum is her brother's enemy and one of the most wanted guys at school, but she can't help feeling butterflies whenever he is around. And the more time she spends with him, the more she realises: Just one kiss might not be enough. Book #1 of the 'hearts' series
