Just be cool, Jenna Sakai
(Book)

When boyfriend Elliott breaks up with Jenna Sakai before Christmas break, she just about convinces herself that relationships are for suckers and she is better off without them; but unfortunately she finds herself in competition with Elliott for a journalism scholarship, and worse her first assignment for the newspaper club is to write a personal essay, which is difficult when you are someone who prefers to keep your emotions bottled up--and than there is Rin Watanabe, a boy as stubborn as Jenna herself, and a mystery that Jenna cannot help but investigate.
