Of all the boys she could be falling for, Tammy Rin just had to fall for one person utterly off-limits—her older sister Cat's boyfriend.
Cat is everything Tammy isn't: popular, confident, and effortlessly perfect. And of course, her boyfriend, Connor Lu, is as swoon-worthy as he is infuriatingly handsome. But after one too many days third-wheeling their dates, Tammy starts to realize that her feelings for him are growing.
As if that wasn't complicated enough, enter Dylan, the new transfer student with his laidback charm and quiet eyes. Along the way, he falls for Tammy, but she's not sure she can feel the same.
Caught between sisterly guilt and her heart's desire, Tammy struggles to keep her world from unravelling.
But when her heart hovers dangerously close into forbidden territory, she'll have to make the hardest choice of all—between family . . . or the boy who makes her heart trip and fall.
