Harry Potter fans are getting two brand new books to add to the shelf, and they’re officially confirmed this time.
Bloomsbury Publishing is expanding its Pocket Potters line with a pair of new titles focused on Minerva McGonagall and the Weasley twins, Fred and George, according to Collider. Both books are due out in February 2027.
They’re aimed at younger readers, but as anyone who collects the existing Pocket Potters range will know, that’s unlikely to stop grown-up fans adding them to their collections too. Reports, including from LADbible, say the new editions come with “hidden details” woven into the pages, though the publisher hasn’t yet spelled out exactly what those will be.
Why it matters
The timing isn’t a coincidence. The announcement lands just weeks before HBO’s new live-action Harry Potter series is due to premiere on Christmas Day 2026, kicking off a fresh wave of interest in the wizarding world.
It’s also been a busy year for Potter fans generally. Audible released a lengthy full-cast audio edition of the series earlier in 2026, and the first trailer for the HBO show has already dropped. Kit Harington, best known for playing Jon Snow in Game of Thrones, has joined the HBO series for season two as Gilderoy Lockhart, having previously voiced the character in an audio adaptation.
Speaking on Josh Horowitz’s The Happy Sad Confused podcast, Harington revealed that Harry Potter audiobooks played an unexpected role in his own life. He said listening to them helped him get to sleep after he got sober, describing how his mind would otherwise race at night. “My brain is incredibly busy, especially at night… When I got sober, that got especially bad. So I started listening to Harry Potter audiobooks, and now they’re the thing I listen to every night,” he said.
The appetite for all things Potter also shows up in the numbers. JK Rowling’s firm Pottermore Ltd, which handles digital sales of her e-books and audiobooks, turned over £54.3million in the year to the end of March, up from £48.8million the year before, according to The Sun. That works out at roughly £148,767 a day, with pre-tax profit rising to £17.2million.
The original seven-book series, published between 1997 and 2007, has sold more than 600 million copies worldwide and been translated into 85 languages, per the Daily Express. The final instalment, Harry Potter and the Deathly Hallows, sold around 2.7 million copies in the UK alone within 24 hours of release.
What happens next
The two new Pocket Potters titles are expected in bookshops in February 2027, a couple of months after HBO’s series debuts on 25 December 2026. Bloomsbury hasn’t released cover art or further details on content at this stage, so fans will have to wait for official previews closer to publication.
For now, what’s confirmed is this: two new McGonagall and Weasley-twin-focused books are coming, they’ll sit alongside the existing Pocket Potters range, and they arrive right as the franchise gears up for its biggest television moment since the original films ended.
