The announcement over the intercom had been received with unabashed cheers and whistles, and was followed by a mad scramble of books and uneaten lunches being thrown into backpacks.Sheridan couldn’t share in the enthusiasm, though. A snow day meant nothing with her sister April gone.Outside, the small fleet of buses had been lined up on the street, their engines idling, great clouds of exhaust rising up to meet the heavy snow.Now she was home, safe and warm, curled up on the couch in her sweats reading an introductory book about falconry that had appeared in their mailbox the day before in an envelope addressed to her.
