Dating back to 1949, the Cheltenham Literature Festival is one of the oldest events of its kind in the world. For ten days every year, the town becomes a hub of literary action.
From poets to comics to politicians - and everything in between - the festival offers a lot for book lovers and this year is no different.
So who are the big names drawing in the crowds and who should you look out for? Making the most headlines - before the event even started - is Hillary Clinton. The former American presidential candidate is making one of just two UK appearances at the festival. On the last day of the festival, she'll be discussing her new book What happened which tells the story of her defeat to Donald Trump in the 2016 presidential race.
Fresh from receiving an honorary degree from Bristol University earlier this year, Matt Lucas will be speaking as the festival gets underway tonight (Friday).
He's one of many celebrities at the festival promoting a new autobiography, albeit one that promises more laughs than most!
If health and fitness is your thing, then Plymouth's own Tom Daley is offering hints and tips as he talks about his new book Tom's Daily Plan.
The Olympic diver will be making an appearance on Saturday.
And staying with sport - or sporting mums - Judy Murray will be sharing her story of what it takes to raise champions.
Mother of tennis heavy weights Andy and Jamie Murray, Judy Murray also reached a new audience when she made it all the way to week eight on Strictly Come Dancing.
But that's just a handful of the many famous faces that can be spotted over the next ten days.
