THURSDAY is World Book Day – the biggest annual celebration of books and reading in Britain.

And to mark the occasion The Hunts Post has teamed up with Little, Brown Book Group to give away lots of books.

We have 15 sets of four paperback novels by well-known authors for you to win – each set is worth more than £30.

The first is Love Over ­Scotland, by Alexander McCall Smith, in which the author returns to follow the characters who live in apartments in Edinburgh.

This instalment tells the story of six-year-old ­Bertie as he perseveres in his heroic struggle for balanced good sense against his insufferable mother, going as far as to make a shortlived bid for freedom on a trip to Paris with the Edinburgh youth orchestra. Domenica sets off on an anthropological odyssey with pirates in the Malucca, and Big Lou, eternal source of coffee and good advice, has love and heartbreak on her mind.

The next is From Potter’s Field, by Patricia Cornwell.

The body of a naked woman is found propped against a fountain in New York Central Park. Calling on her reserves of courage and skills, and the able assistance of colleagues Marino and Wesley, Dr Kay Scarpetta must track down the killer.

In Lazy Bones, by Mark Billingham, someone is ­writing to convicted rapists in prison, befriending them and then brutally killing them when they are released.

Det Insp Tom Thorne must discover the link between these killings and a murder (or suicide?) that took place 25 years before – a tragedy to which the only witnesses were two small children, now nowhere to be found.

Eden Close, by Anita Shreve, sees Andrew, an advertising executive in his mid-30s, return to his hometown in upstate New York for his mother’s funeral.

He does not intend to stay in the rural backwater he left 17 years before, but the dreams and memories persist, and in the darkened farmhouse he re-lives that hot, bloody night when Eden Close was blinded – by the same gun that killed her father.
