for Under Shifting Glass by Nicky Singer
Jess has a secret: a mysterious glass flask she finds in an heirloom desk's hidden compartment. Its surface swirls with iridescent colors, like something's inside, something almost like a song, something with a soul. No one else sees anything under the shifting glass, but Jess is convinced there must be some kind of magic in there. And when her twin brothers are born critically ill, Jess begins to believe that the force within the flask just might hold the key to saving her brothers—and her family. In this emotionally rich novel, award-winning author Nicky Singer crafts a world of possibility that is steeped in hope and the power of love.
