Determining the exact word count for Sarah J. Maas's A Court of Thorns and Roses (ACOTAR) is tricky because it varies depending on the edition (hardcover, paperback, ebook) and even the specific formatting used. Different publishers might have slightly different pagination and formatting, leading to minor discrepancies in the word count.
There's no single definitive answer readily available online. However, estimates from various sources place the word count somewhere in the 70,000-80,000 word range. This is a typical length for a fantasy novel of its genre and size.
To get a more precise count, you would need to use a word-counting tool on a specific digital edition of the book, but even then, it might differ slightly depending on the version. Keep in mind that this number is an approximation, and minor variations are expected.
