The Canary Chronicles by Anne Smith Burton

After moving to New York to attend Columbia University, Kyle Sullivan's life became a narcissist's dream. She treated New York's nightclubs, restaurants and theatres as her private playground and its beautiful men and women as her personal amusements. She had a grudging appreciation of concepts like 'being in love and forever', but generally thought such things were for other people. It wasn't that she didn't believe she could fall in love, she just didn't see why she should limit her options by committing to one person. Then Kyle learned the redemptive qualities of love the hard way, by losing it.
