TLDR, despite the HEA, this was a bleak, frustrating read that kept trying to justify so many nope nope nope moments.
So the blurb says this book has "dark themes", but I'd go further and say it's a dark omegaverse. The interactions bw the MMC head alpha and FMC equate to r*pe and abuse for basically the whole first half of the story. Why? Bc that alpha repeatedly drags her off somewhere to "rut" her even though she repeatedly clearly struggles, pleads with him to stop, describes how she feels so gross and used afterwards, etc. Oh, and these struggles/pleads each time only stop once she's so pheromone drugged that she begins to "enjoy" it. Moreover, although the alphas constantly mention how they respect and love their omegas, they treat them like possessions, demand unconditional obedience, don't bother communicating, etc.
Example:
(Cam, Aris, and Han are the MMC Alphas. Brin is a MMC omega. Violet is the FMC omega.)
[“Are you allowed to fuck the omegas whenever you want?” Cam asks, and my eyes go wide, surprised that’s what he wants to know. “I mean, I know you can’t just fuck them when they’re in distress or in pain, but you and Han seems to just grab them and do whatever you want…” He trails off and I can imagine that curious, boyish look on his face. It’s a guilty expression, one that says he feels like shit but still wants to know.
“That’s not how it works.” Aris chuckles. “Stop it. I’m not making fun of you. Just listen.” Someone shifts on the bed, messing with his blankets. “As your senses take hold, you’ll be able to tell when an omega needs to be tended to.”
“I could still smell slick when I thought I was a beta,” Cam says. “All betas can smell slick.”
“It’s more than that.” Aris’ voice drops, slipping into his training mode. He’s like this with our new recruits too. Patient and understanding, trying to make sure everyone does their job correctly. “It’s not just an omega’s scent, but their energy. The way they move and the look in their eyes.”
“I’ve heard both Brin and Violet say they don’t want it. But you and Han…” He hems and haws for a second before finally saying, “You fuck them anyway.”
“It’s difficult to describe,” Aris says, and I picture him grimacing. “An omega might verbally reject your advances, but not tending to them could result in them slipping into distress or could leave them in physical pain. Omegas simply don’t like to admit things sometimes. They keep their emotions bottled up. So even though an omega thinks they don’t want to be touched, doesn't mean that’s what is best for them.”
Cam hums as if understanding. “How long do you think it’ll be before I’ll be able to tell what an omega needs?”] - here Bran interrupts the conversations bc he needs to talk to Aris.
