Daisy, otherwise known as Daze, keeps hearing her dead mother's voice.

Sometimes it's because of her dad, who likes to watch old home movies when he can't sleep.

Sometimes it's because of her brother, who was too young to remember Mom, and needs to be reminded by looking at photographs and watching videos.

Sometimes it might just be her mind trying to work out what her therapist would call "e;issues."e; But this time, it is none of those things.

It's something much more wonderful and much more terrifying, something Daze never thought possible. And it might allow Daze to do what she couldn't years ago: save her mother's life. Rune Michaels, the visionary author of Genesis Alpha, plunges headfirst into the waters where science, family, and memory meet, and emerges with a powerful and fascinating story about loss and survival that challenges everything we think we know about the people we love.
