I agree it seems a little shoe-horned to make her a classical witcher. I hope it’s not just to give her the title, because she could easily be the protagonist, and/or have the job of being a witcher without the trial of the grasses. She was given the training and education of a witcher, and has magical powers of her own already. Receiving the trials would be a huge deal, narratively, to the characters, and to world building. I could easily see this being a fumbled corporate attempt at placating fans that wanted to see geralt, without any regard for the characters or world building. (Similar to “Rey Skywalker” having absolutely no business being a Skywalker). But that’s all speculation. If it’s treated as a major plot point, and not done just for the hell of it, it could still be good.
Atkinson hyperlegibile is hands down the best for reading ebooks. It was designed for visually impaired people, but it’s also super easy on the eyes for everyone else. I read so much faster and more comfortably with this that I can’t imagine using anything else.
