Logan, a character in "The Freshman" series, is an upperclassman at Hartfeld and a member of Hartfeld's football team "Knights". He first appears in Book 1, Chapter 5. Your Character is able to meet him in Chapter 1, if she wears a bikini and goes on the 'slip 'n slide'.
Logan has black hair, light skin and brown eyes. He wears a black-grey sweater.
Darren & Chris
Darren and Chris are Logan's football buddies. They're coming along very well. In Book 2, Chapter 14, it's mentioned that Logan and Darren are also roommates, as Chris tells he'd spend the night at their place.
Becca and Logan are good friends. She once cussed an ex-girlfriend of Logan, who cheated on him, in front of the entire dorm.
Given that he hasn't appeared in The Sophomore yet, it is likely that he was a Senior during the events of The Freshman.
