Sanctuary remains one of the best books I've ever read, so although I was excited to hear there was going to be a sequel I was a little bit nervous as well. However, Bittershore was a fitting continuation of the first book with additional insights into characters I already loved. The beginning was a little slow and it took a beat to get back into the world, but after the first few chapters I was once again gripped.

I received a copy from the publisher in exchange for an honest review

I really enjoyed Sanctuary, describing it as: 'A terrifyingly topical book about a literal witchhunt shows how easily hate, paranoia and fear can turn communities against each other. Parallels with brexit, and Trump's America abound in this clever, tightly plotted novel.' I had hoped for a sequel but after 5 years had pretty much given up so you can imagine how delighted I was to see this pop up on Netgalley. So, did Bittersweet live up to expectations? Well, yes and no...
Yes: we delve deeper into this cleverly thought out society where witchcraft is both legal and tightly controlled, learning more about those controls, those who circumnavigate them, the resentment it causes and the dangerous underbelly of magical society. A new danger intensifies, and the tense, taut plotting really ratchets up the tension to almost unbearable levels. We see the aftermath of societal breakdown with relationships and friendships in tatters and individuals unable to face up to their own part in the tragedy and the events that caused it.
No: Too many characters and not all need their own POV. Sarah, the protagonist feels almost unbearably naive, the decisions she makes plot devices rather than making any real sense, the red herring plot in many ways unneccessary. I did find myself skim reading at times which, after a five year wait, was disappointing.
Would I recommend it? Despite some reservations, yes - for the worldbuilding, the continuation of the story and the set up for the next book.
