"The Dawn of Amber", "Chaos and Amber", "To Rule in Amber" and "Shadows of Amber" by John Betancourt
Not as good as I remember Zelazny's Amber novels were, but I haven't read those in a while (I have reread other Zelazny works, though, and they were roughly as I remembered them, so...)
Betancourt's biggest problem is that he doesn't write people very well, and he's downright terrible at writing women. The female characters in the book fall into three categories: 1. Beautiful relative 2. Beautiful and trying to sleep with the main character 3. Hideous but politically useful. Male characters have more variety, but we're just told they have character traits, for the most part. The characters almost all read the same in dialogue.
Overall: interesting ideas, poor execution.

Further back I've read.... Wait, I can't seem to find my ever having posted here about Meghan Ciana Doidge's Adept Universe. So there's 16+ books I've read in the last five years that I've somehow managed to avoid raving about, despite the fact that I loved them. The series has grown better by leaps and bounds as Doidge has gained skill as a writer and fleshed out the world beyond just basic supernatural romance stuff. Cupcakes, Trinkets and other Deadly Magic is the first book in the universe, and it's good, but IMO it's not until the Oracle series spins off with I See Me that the world starts to be something remarkable and step beyond just being solid urban fantasy chick lit. I love all the main characters a bunch, and I'd be hard pressed to choose a favorite protagonist. I'm 4 or more books behind the latest published, but I'm looking forward to catching up, though my To Read list is pretty long.
The books I've read thus far are from three series within the Adept Universe. The Dowser series follows Jade, a half-witch who owns a bakery in Vancouver, after a series of supernatural murders make her life much more complicated and she discovers she's not half-human, and that her full-witch mother lied about who her father was. The Oracle series follows Rochelle, a teenage who just aged-out of the foster system, knows nothing of the magical world, and discovers that the headaches and hallucinations she's suffered from all her life are actually magical visions of the future, the legacy of her mother who died when she was very young. The Reconstructionist follows Wisteria, a witch who specializes in magical reconstructions of past events, and has trouble when her abusive uncle's influence resurfaces in her life. There's also the Amplifier and Misfits series, but I haven't gotten to those yet, though I think I've met the characters; the various series are tied together.
Reading Cupcakes... it would be easy to dismiss it as a Twilight knock-off, complete with vampire and werewolf love interests, but the series has progressed far beyond that. Jade isn't a blank slate, and is actually quite a power fantasy in her own right. She starts as a competent adult, at least by ordinary standards, having a successful business, and while she is overwhelmed by magical forces far beyond her own, she eventually moves from being dragged by the tides of the plot/fate, onto having significant agency in her world.
These books are currently my favorite series.
