I looked at him with my eyes narrowed " seriously Sia Cheever? you couldn't come up with a better name?"
he raised one of his eyebrows "would you have preferred Hermoine Granger or something?" he mocked.
I rolled my eyes "whatever"
" my cover is my identity and from today I am Sia Cheever," I said
...
