This book is about a boy who believes: hope never dies! After his dad left the family, Dan Hope's life turned upside down: his mother became sad, his sister Ninja-Grace became mischievous, and he could not fulfill ten of his cherished wishes even Saint Gabriel, in whom Daniel’s friend Jo Bister believes so much. But suddenly... what if dad returns, everything will fall into place again: mom will be happier, Ninja-Grace will again become Princess Grace, and wishes will begin to come true one after another? Dan Hope lives in hope of this meeting. He opens his email and begins to write: “...Please answer my letter as best you can. I found your address on the TV channel's website. I'm smart, huh? Mom says that it was me who fell in love with her, but I’m not entirely sure that this is the absolute truth. Love, Dan.”
