Hooked — Catherine Greenman

Thea Galehouse has always known how to take care of herself. With a flighty club-owner mom and a standoffish, recovering-alcoholic dad, Thea has made her own way in her hometown of New York, attending the prestigious and competitive Stuyvesant High School. But one chat with Will, a handsome and witty senior, and she's a goner -- completely hooked on him and unable to concentrate on anything else.

Always worried that she loves Will more than he loves her, Thea is pleasantly surprised when their romance weathers his move to college and Will goes out of his way to involve her in his life. But then, Thea misses a period. And that starts Thea and Will on a wild ride that neither of them could have possibly prepared for. When they decide to keep the baby, their concerned parents chip in what they can to keep Will in school and give both teenagers a comfortable place to raise their child. But when a freak accident leaves Thea shaken and threatens to upend their little family altogether, Thea is forced to turn to the last place she would have chosen for comfort: her stiff, uncompromising father.
This smart, touching first novel brims with realistic, beautifully drawn characters, and reminds us that love is never as easy or predictable as we might like it to be.
