Spring break is supposed to be the last chance for some carefree fun before graduation, but for Felicity, it becomes another form of education. Felicity Stone is a brilliant chemistry major who can tackle the most difficult of chemical equations, but she can't figure out simple social interaction. When she's left on her own for spring break, she accepts a gorgeous stranger's invitation to play his fake girlfriend at his brother's wedding. Lucas Tanner is dreading his brother's wedding because his ex-girlfriend is the maid of honor. After that relationship, he was tired of disasters and called a moratorium on dating. So when he meets deliciously intriguing Felicity, he thinks he has a solid plan: she'll pose as his girlfriend and he'll teach her the subtle art of flirting. Once his lessons draw out Felicity's natural charm, Lucas doesn't want her to use those skills on anyone else. Can he convince her they have perfect chemistry?
