The deepest breath

Stevie is eleven and loves reading and sea-creatures. She lives with her mum, and she's been best friends with Andrew since forever. Stevie's mum teases her that someday they'll get married, but Stevie knows that won't ever happen. There's a girl at school that she likes more. A lot more. Actually, she's a bit confused about how much she likes her. It's nothing like the way she likes Andrew. It makes her fizz inside.
