My one liner about this book can be boiled down to: if the Lost Apothecary were actually good. 

While the parallels are obvious, my enjoyment of the two books was drastically different. I DNFd the Lost Apothecary due to the writing style, which grated on and annoyed me. I preferred the style of Weyward much more, and generally found the themes more interesting. The structure is similar: we follow three related women, in three time periods (past and present), who are connected by a deeper thread and who draw on similar strengths to overcome their struggles. 

Weyward is a book that you have to be in the right headspace for. A lot of bad things happen to the women we follow (both when they're grown up and when they're girls) and it can be harrowing to read about. I found the handling of these topics to be sensitive and nuanced, and generally found their stories relatable and compelling. I suspect that, based on your own experience, your mileage may greatly vary. 

Recommended if you're interested in following multiple narratives relating to the concept of "woman as witch", reproductive rights, and connections with nature. 4.25 stars on SG rounded down to 4 on GR. 

Note that reading this did lead me to getting really into the songs "labour" and "burn your village" for a solid three weeks.
