The plot is just FULL of holes. Tarn is supposed to be a really bright girl, yet she misses all the clues that something isn't right. It's just sooooo completely unbelieveable that Caz just instantly falls in love with and pursue Tarn. He's supposed to be this typical rich, sophisticated, playboy-type hero, yet he's completely patient and almost blindly foolish about Tarn. Also, the facility that the cousin is staying at. So much of this book would not exist if they were honest with Tarn about her cousin's situation. And, maybe they wouldn't tell Tarn since she's not exactly next of kin, but you'd think that they would tell the mother. But no, everything about the cousin's condition, therapy, situation, etc. is all kept hush-hush. Well, no wonder Tarn thinks that her cousin is in trouble. I mean, seriously. It turns out that the cousin has always had an inferiority complex towards Tarn. And the cousin has apparently been a delusional stalker towards Caz. So, you would think that the head "doctor" at the facility would talk to Tarn and prepare her and explain what she should and should not be saying to her cousin. But do they? No.
