Jennifer Tatum has always been the girl who can make anyone smile. She's the friend everyone counts on, the one with a quick comeback, an impossible amount of optimism, and a smile convincing enough to hide everything she never talks about. But some stories refuse to stay buried. As senior year begins, secrets start unraveling, friendships are tested, and the people Jen trusts most begin keeping secrets of their own. Between unexpected betrayals and impossible choices, she's forced to face a question she's spent years avoiding: How long can someone pretend they're okay before everyone notices they aren't? Then there's David Beckett. The kind of person who always shows up. Funny without trying, kind without expecting anything in return, and the first to make sure everyone else is okay before thinking about himself. While Jen is busy carrying the weight of the world on her shoulders, David quietly becomes the one person she never has to pretend around. Steady, loyal, and endlessly patient, he's the reminder that sometimes the strongest kind of love isn't loud-it simply stays.

Sienna Lynch has one rule, never get involved with the Hollands. As the daughter of Tadgh, she's heard every warning there is. Lorenzo Holland's a mess - fighting demons no one wants to face.

Caoimhe Kavanagh doesn't do feelings-especially not for Liam Gibson. He's loud, charming, and hopelessly in love with someone else. But somewhere between the teasing and the late-night chats, she falls. And the worst part? He doesn't even see her.

"I'd do anything for her. I would kill every last fucking person on this planet, if she asked me to. And I wouldn't even question her about it. All she had to do was ask." - Zayn Banks
