The Princess Diaries by Meg Cabot.

My Almost Epic Summer by Adele Griffin.

What My Mother Doesn't Know by Sonya Sones.
Sophie describes her relationships with a series of boys as she searches for Mr. Right. This novel is in verse form, so each "chapter" is a poem. Meet Sophie. She sees herself as the too-tall "Mount Everest of teenage girls," who, along with her friends, often suffers from "lackonookie disease." She's dating smoky, sexy Dylan, covertly chatting online with "cybersoul"-mate Chaz, and secretly nursing a crush on sweet, geeky Murphy. Her two best friends are closer to her than sisters, and she
"hates hating" her soap opera-addicted mom, wishing "she would show half as much interest in my life as she does in Luke and Laura's.” (description from Amazon).
Eva Underground by Dandi Daley Mackall.
In 1978 high-school-senior Eva Lott leaves her boyfriend and her comfortable life in the Chicago suburbs for Communist Poland, where her father is teaching in the underground education movement. Coping with the recent death of her mother from cancer, Eva now has to contend with the boredom and loneliness of living in a foreign country. After a botched attempt to run away and make her way back to Chicago, Eva develops a friendship with Tomek, a young underground leader, and a
romance blossoms, giving her a desire to stay. (description from Amazon)
