Book Boyfriend by Lucy Vine

Jemma has lived a thousand lives through books. The only life she isn’t living is her own.
That is, until the day she finds a note from a stranger in her favourite library book. When she replies, the pair begin a longhand conversation about their love of novels that sees Jemma finally coming out of her shell. Is she ready to fall in love for the first time – with someone she’s never met?
 
Clara has always run away from her problems, but this might finally be one she can’t escape.
Everyone wants to know what happened to Clara in America – but Clara isn’t talking. Instead she’s focusing all her energy obsessing over a hot new actor, starring in the TV adaptation of her twin Jemma's favourite book. Soon, Clara is reading every interview, trawling his social media, and following him to showbiz parties in the hopes he’ll notice she’s The One.
 
As the sisters fall hard for two men they’ve never met, it’s time to ask the question: Can either relationship survive the real world?
