Division (near-future SF)
"The Baby" (free SF short story, possibly a prequel to Division)
This book is set in an afterlife: what sort of afterlife, the reader may decide.
Cassidy stood tall and watched the wave approaching. Fifteen was a good age for confronting the ocean. That morning she had been five years old, playing happily in her sandbox; from sand to beach, from beach to ocean waves, seemed a natural progression.
The wave loomed above her, glowing turquoise and green. She dove under the crest, through the surging water, and popped up behind the swell, bobbing in the follower waves. The water held her and rocked her; over the hiss and roar of the waves, she could hear the distant squawk of seagulls. All around was the smell of seaweed and salt and sunshine.
Once, her mother had held her, carried her, rocked her, surrounded her with love and safety. She had no idea how long it had been, but she remembered. Remembering, she let herself slip younger as she floated on the swells. But larger waves were coming, so she grew again, six, ten, sixteen; then caught a wave and rode it into shore.
