Both really, as they are same universe. I stopped reading around...I forget the name of the book, but I think it was like 2 books after the Fey just decapitated that senator or whatever in public, and broke all political ties. I vaguely recall Mercy going to a Native American reservation about some Coyote stuff? That was the last one. I had a hard time stomaching Mercy, she was just so insufferable. I liked the pack she was tied to, just her, not so much.
Frankly Patricia's 2 series are basically same premise. Super violent Alpha, in love with a woman who Just So Happens to not be mystically compelled to obey orders from the wolf pack structure, and is in a position to call out all the big scary wolves in a chiding tone, because girl power or whatever, and everyone just falls all over them. In the case of Anna the Omega, quite literally fall at her feet in worship. Plus I wasn't a huge fan of the fact that both female protags were rape victims, though I do think her portrayal of some of the aftermath, the emotional damage when it came to Mercy, was done pretty well. It felt ugly and real in it's presentation. Like I genuinely felt "ok yeah, she's pretty fucked up from what happened, I buy that. This feels like real trauma." But yeah, I suspect, that she's perhaps an abuse survivor herself, given how it's such a key part of both her main characters, and her descriptions of it, the effects feel....experienced. But, it still makes for some repetitive plots, that I got tired of. Which sucks because I REALLY liked her work for a while there. Like I REALLY enjoyed her mystical pack structure, and their mystic powers and how they were represented, so much so, that I firmly believe she used to play Werewolf: the Apocalypse and/or Forsaken, given how similar the pack magic is to gifts in those game lines.
But then her writing just kind of ...lost me. I dunno. I might try out some of the books I'm sure she's written since I stopped, but I'll probably never pick up the Mercy series again. If she would just remove mercy, and let me have a story about that pack, I'd be thrilled. The Alpha/Omega series, was fine as it was for the most part, Anna wasn't anywhere near as annoying as Mercy, despite having the same archetype.
Yeah the constant posturing of the dominant wolves could get tiresome, given how much page time would be devoted to dealing with it. I'd like to see less of that, and just get to the story. But usually that was only a problem when new wolves were introduced, so they had to have a shaking down of the pecking order. I get it, the reason for it, but yeah, not something I care to read book after book. That adds up to a lot of hours of my life listening to audiobooks about, well, literally alpha dudebro type people, flexing and posturing. *shrugs*
