Marla Fontaine AKA Befana is a resident of Poe Cottage. She was recruited heavily by Poise for Venus Inc., but refused, finding her studies more important. Her code name is a reference to an Italian tradition called a 'Christmas Witch'. She has a fairly major crush on Tansy Walcutt.
From The Boys of Summer:
"You remember Marla Fontaine? Going to be a senior next fall?"
A frown creased Tansy's brow as she refilled the glasses of champagne. "Yeah. Wizard. Tall and brunette. Extra curvy. Wears her hair very long and dresses rather ... provocatively. Why?"
She has green eyes.
