Critical Maas: Is this real life? Is this just fantasy?

You would be forgiven for thinking that bookshops were caught in a landslide of fantasy fiction in 2024 with authors such as Sarah J Maas and Rebecca Yarros dominating the top end of the fiction charts – as seen in our Author Review of the Year in last week’s issue (The Bookseller, 17th January 2025). It was not just the spicy side of the genre represented either, with JRR Tolkien’s sales rising 21.3% year-on-year through Nielsen BookScan’s Total Consumer Market and Brandon Sanderson appearing inside the top 50 authors of the year for the first time. Is this a trend that’s going to continue into 2025 – and, if it is, which series should we be keeping our eye on?

It is timely to start with Rebecca Yarros, as the third book in her Empyrean series – Onyx Storm – is published this week, while Fourth Wing and Iron Flame are sitting atop the Fantasy charts so far for 2025.

First published in hardback in 2023, the first two books in the series were released in paperback in 2024, with Fourth Wing placing 11th in the full-year chart, selling just shy of 250,000 copies. The paperback of Iron Flame was only released in November and has shifted 78,586 copies in its first nine weeks – 7.4% down on the equivalent period for its predecessor.

With Yarros’ threequel set to storm the Original Fiction chart next week – and two more books expected in the series, although not yet announced – it is likely that Yarros will continue to be an immovable presence in the chart, not just in the fantasy genre, but at the top of the Fiction charts as well.

While Yarros tops the fantasy chart so far for 2025, it is Sarah J Maas who dominates it, taking five of the top 10 spots. With TCM volume sales of 1.3 million units in 2024, the author of the A Court of Thorns and Roses series rooted herself into second place in our authors of the year chart with sales of £13.2m.

The bestselling fantasy hardback title at the moment could be the start of the next big thing

So far this year, Yarros’ value has already reached £483,676 – up 88.9% against the first two weeks of 2024 – and with fans eagerly awaiting the paperback release of last January’s House of Flame and Shadow, as well as the fifth ACOTAR novel, a surprise 2025 release or two could see Maas’ sales increase further still.

The bestselling fantasy hardback title at the moment could be the start of the next big thing. First published at the beginning of December, Quicksilver – the first instalment of Callie Hart’s Fae & Alchemy series – has sold 34,417 copies, with 17.9% of that coming in the past two weeks. A sequel is due later in 2025 but, so far, no date for the paperback edition has emerged. Another author to keep an eye on is Sarah A Parker, whose When the Moon Hatched is one of just three hardbacks inside the fantasy top 20, despite being first published back in June. It has just topped £1m worth of sales and consistently appears in the e-book charts provided by BookStat. The paperback is due in May, while the second book in the Moonfall series will be published in October of this year.

While 19 of the 20 listed here are romantasy – only Gregory Maguire’s Wicked bucks the trend – they are not the only sub-genre of the market on which to keep an eye. The third bestselling fantasy author of the moment is Brandon Sanderson, whose Cosmere universe has delivered £135,763, while Tolkien’s romance-free books have notched up £109,753 – though it is worth noting even when Tolkien and Sanderson’s sales are combined with second-placed Yarros, they still cannot top Maas’ total.

So far in 2025, the SFF sub-genre – which is largely driven by fantasy titles – has already racked up £3.2m, nearly a third up on the beginning of 2024, indicating that bookshops across the country may soon need to rebalance their space as readers continue to seek to escape from reality.
