A higher percentage of children and young people successfully completed the Summer Reading Challenge in Worcestershire compared with any other area of the West Midlands.
In total, 2,959 participants in the county read all six books between June and September last year, new figures show.
It means 74.2 per cent of starters completed the challenge. The overall regional average was 62% so Worcestershire was well above that figure.
The challenge, run by the Worcestershire Libraries and Learning Service, was launched at National Trust Croome.
Councillor Lucy Hodgson, Cabinet Member for Communities, said: "I'm delighted with the completion figures for 2018.
"To have almost 3,000 children and young people reading six books over the Summer Holidays is a fantastic achievement and they should be proud of themselves.
"These figures just go to show how popular and successful the Summer Reading Challenge is here in Worcestershire and I look forward to this year's challenge as I think it'll be even bigger and better.
"I would also like to thank all library staff involved and the teams of volunteers who gave up their time for free to help out with the challenge."
Worcestershire had the highest number of young volunteers in the West Midlands, at 164.
The Summer Reading Challenge is the UK's biggest free reading for pleasure promotion for children and young people aged four to 12 and takes place every year.
Run by The Reading Agency, the theme this time around was Mischief Makers in celebration of The Beano's 80th anniversary.
