The Space Chase, Summer Reading Challenge 2019 runs from Saturday 13 July to Saturday 14 September. If you are aged 4 to 11, you can sign up at a Barnet library near you during the summer holiday.
For one afternoon only at Finchley Church End library, meet Buzz Lightyear and Princess Leia, courtesy of Big Time Academy.
They will be visiting the library from 2pm to 4pm, so get your cameras ready for a selfie with them once you've signed up for the reading challenge.
Dress up as your favourite space character to register for the challenge if you like!
