Tremble (Philia Players, 2) by Giuliana Victoria

Aiyana Kaan is the best friend everyone needs. She's self-assured, a total badass biomedical engineer, could kill you with her witty comebacks alone, and is loyal beyond measure—sometimes, even to a fault. When she moves back to Philadelphia after five years away, she can't seem to fight the attraction throwing sparks between her and Kas.

But who could blame her? Not only is Kas a talented hockey player, but he’s also sexy to dangerous degrees and has made his feelings toward her crystal clear.

So, what's the hold-up? For a start, Kas is her best friend’s brother. But that’s not where it ends. There's more to their story, including a secret Aiyana’s holding close to her chest. And while she’ll fight tooth and nail to keep Kas from ever finding out the truth, he shows no signs of giving up any time soon. Or ever really.

Kassian Narvaez is the brother of the century with a sneaky habit of playing matchmaker. But if he's so good at setting others up, why is he still single?

The truth? This sweet and funny guy only has eyes for one woman. Kas has been pining after Aiyana since they first met in middle school, and while he hasn't quite figured out why Aiyana changed her tune so suddenly, he's determined to get to the bottom of it.

Will Aiyana finally let herself be happy with the man she's loved her whole life, or will Kas be destined to continue his weekly therapy sessions in the hopes of finding a solution that sticks?
