Lotz takes what could be a confusing concept and makes it fun, heartbreaking, and eminently readable all at once. Bee and Nick’s emails are witty and romantic, while their supporting characters are entertaining in both worlds. Lotz manages to combine romance and science fiction into a book that will produce laughter and tears. Readers will find themselves wondering how, or if, Bee and Nick will end up together until the very last pages.

A thought-provoking and clever genre-bending blend of romance and science fiction.
