Actual Rating 3.5
While I enjoyed Whispers in the Dark, it is one of those books where my primary thoughts are mostly criticisms and somewhat conflict with my overall enjoyment of the book. Regardless, here we go...
My main qualm is that I didn't connect with the majority of the characters. I struggled to finish Boone's, Titus', Mattox and Garret's chapters, and only really grew invested in Jensen and Solana when they paired up (fairly early in the narrative). I liked Gabrielle instantly, though she takes a while to appear in the story. This resulted in a significant urge to skim through any chapter not focused on Gabrielle, Solana or Jensen. Garett's best chapter(s) was when (Redacted for spoilers) died and he gained real, emotional agency I could empathize with. I believe that is the root of my disinterest in the other characters, they themselves lacked intense emotional investment in whatever endeavor they were attempting. This is exacerbated by the fact that they lacked someone or something to express chemistry with; Jensen and Solana are constantly interacting and changing in their interactions as they feel one another out and adapt. Yes, the others interact with other people, but their relationships lack the traction Solana and Jensen have. Garret and Miriana tend to get along, Boone and Sithig get along, even Titus and that one scholar (whose names escapes me ATM) get along. This dampers the story not only because it makes their interactions less interesting, but it removes the opportunity for them to express their personalities in a meaningful way. But when the characters are allowed to express themselves (Jensen, Solana and Gabrielle) they are excellent and very enjoyable.
I have two other minor criticisms. First, I found the magic systems rather ambiguous; the author would label a particular individual a cryomancer, or a pyromancer (indicating an innate, specific talent), but then display them utilizing other spells. They further complicate the matter by indicating certain magic types incur privileges, (healing and negation) which doesn't work if mages can choose the magic they practice. (A related, but ancillary criticism is that the fantasy races felt a little generic and included mostly for name recognition. The Author mention orcs, ogres, werewolves, elves etc and that is the extent of the world-building provided for them, which results in their presence not truly enrichening the narrative or world.)
Finally, the author used the same conceit in all three potential romances (redacted for spoilers) namely that they all believe the other member disinterested, and misinterpret their actions or dialogue to supplement that belief. This both diminishes character interaction and waxes repetitive.
There's also the fact that almost every main male character suffered from patriarchal abuse, which made me wonder if it actually an attempt at symmetry rather than an oversight. nothing comes of that in this book, but it might result in the sequel(s).
One of the fantasy elements that does land very well and the various Witches and the way they alter the world.
In conclusion, Whispers in the Dark's strongest suit are its characters when they're allowed to interact in meaningful ways, and there is a strong story behind the, it just takes a while for it to capture the reader.
