Change of Plan - Snippet from Short Story for #WeWriWa #Superhero

Welcome to another Sunday with Weekend Writing Warriors . Meet writers in various genres and read 8-10 sentence snippets of their stories. Find a new author and sample their work. Enjoy!
This weekend, I’m switching to snippets from an unpublished short story in my superhero series. It was originally intended for an anthology that didn’t receive enough submissions. I’m debating whether to expand it into a novella or make an anthology with other short stories. Any suggestions are welcome. 
Here are the first lines (unedited).
Her bookbag slung over a shoulder, Estelle Wright hurried out of the classroom. She maneuvered through the bustling corridors of the Bioscience building, relieved her mid-term was over, and eager to celebrate with her boyfriend. Toby Ryan was not waiting by the exit. She looked around for Rockette. A speckled pigeon swooped over her head, and landed on the low wall alongside the steps. Rockette, the flying horse, was in her covert form. “Change of plan,” the pigeon squawked, “Toby’s got a job. Meet him behind the cafeteria.” Estelle smiled; she had shared a telepathic bond with Rockette ever since the infusions of alien DNA had given them superpowers. “Okay, what’s the job?” she asked, switching direction to march along the path crossing the lawn of Goldman University.

The Secret Supers Series has 3 Books
Reviewers say:“Super girls and flying horses. What more do you need?”

“An enjoyable fun and light hearted entertaining story filled with lots of adventure, interesting characters, monsters and bad guys.”
