Lonely little Jane Margaux finds comfort in her handsome imaginary friend, Michael, a grown man. They delight in spending time at the Regis Hotel in New York City; Jane with her coffee ice cream covered in hot fudge and Michael with his melons. Jane's mother, Vivienne, a famous Broadway producer, is unable to see Jane's imaginary partner. Vivienne only has time for Jane once a week for a trip to Tiffany's to look at jewelry. Alone, except for Michael, Jane is friendless and approaching her ninth birthday. She's devastated when Michael leaves her, promising she'll immediately forget him.

Twenty-three years later, the extremely bright Jane is working for her mother and has written a play, "Thank Heaven," which is her story with Michael. Even though Jane was supposed to forget Michael, she didn't, and fate has thrown them a curve. In between his charges, Michael sees Jane and begins a relationship with her. When a falling out occurs between Jane and her domineering mother, Jane quits her job and goes to Nantucket with Michael. As Michael begins to feel more and more human, he has a premonition that he's been sent here for another reason. It's a shock when that reason becomes clear.

This warm and beautiful tale that James Patterson and Gabrielle Charbonnet have written together provides a wonderful insight into the thoughts and feelings of a lonely child surviving the only way she knows how. Jane is a wonderful character and Michael is loving and funny. To live in the mind of a child is a most enlightening place to be. I couldn't put the book down because I had to know what was going to happen next.
