Stephen is used to invisibility. He was born that way. Invisible. Cursed. Elizabeth sometimes wishes for invisibility. When you're invisible, no one can hurt you. So when her mother decides to move the family to New York City, Elizabeth is thrilled. It's easy to blend in there. Then Stephen and Elizabeth meet. To Stephen's amazement, she can see him. And to Elizabeth's amazement, she wants him to be able to see her - all of her. But as the two become closer, an invisible world gets in their way - a world of grudges and misfortunes, spells and curses. And once they're thrust into this world, Elizabeth and Stephen must decide how deep they're going to go - because the answer could mean the difference between love and death. From the critically acclaimed and bestselling authors David Levithan - who wrote "Every Day" and co-wrote "Will Grayson, Will Grayson" with John Green, and "Nick & Norah's Infinite Playlist" with Rachel Cohn, as well as many other novels - and Andrea Cremer - who wrote the bestselling "Nightshade" series - comes a remarkable story about the unseen elements of attraction, the mortal risks of making yourself known, and the invisible desires that live within us all. David Levithan and Andrea Cremer met each other in Washington, DC, even though that's not where they live. Andrea was pretty certain she wasn't invisible, but David confirmed that fact by introducing her to some other writers, who were all able to see her. Before writing with Andrea, David had never written a novel with a one-word title. His novels include "Every Day", "Will Grayson, Will Grayson" (with John Green) and "Nick & Norah's Infinite Playlist" (with Rachel Cohn). He lives just outside New York City. Andrea's novels include "Nightshade", "Wolfsbane", "Bloodrose", "Rift" and "Rise". She lives in New York City, quite visibly.
