Check out the Christchurch City Libraries Summertime Reading Challenge. It is open to everyone, young and old, and there are great prizes like a tablet, blue tooth speakers, fitbits, and vouchers for Foundation Cafe and the new Riverside Market.
It is super easy to enter, click here for more info and to enter online, or pick up a challenge card at the library.
Still looking for something to read, check out the new Genre Guides. Whether you like fantasy, science fiction, historical, or horror, there are too many for me to list here so do check them out.
