Two sisters find themselves falling for imaginary men . . . but are they both too good to be true?

Jemma has always loved books. Fiction, non-fiction, the dictionary. She has lived a thousand lives apart from, maybe, her own.

Her favourite book is a romance called Too Good to Be True. She's got a first edition and all the special editions, but it doesn't stop her from taking it out from the library whenever she can. Except recently someone keeps taking it out too and she's forever on the waiting list for it. And worse still, one day there is a note from the mystery borrower - scolding her for bending the cover!

Her twin sister, Clara, can't understand Jemma's obsession - surely you should only ever need to read a book once. Clara likes reality and drama - even more so when it's on TV. Her latest infatuation happens to be the TV adaptation of Too Good to Be True. Especially because the actor is gorgeous.

When Jemma and her book thief start to exchange longer and longer notes, and Clara's infatuation grows, both sisters find themselves falling for men they have never actually met.
