*sigh* Where to begin with this disaster...
Dear authors, if your world uses the same damn measurements of time as we do, then for the love of all that is literary, use the same labels. Seconds, minutes, hours, days, weeks, months, years. I still don't know if clicks refers to seconds, minutes, or moments (or maybe all of the above, because that was how the term was used). Sun-cycle is clunky and unnecessary, especially if you use the term "day" at least once in the story. A life-cycle is not used to refer to a generation, but rather somehow a year. And I still don't know what a moon-cycle is, other than how others have referred to the menstruation cycle... could be a month. There's apparently no term for weeks, just mentions of "several dozen sun-cycles" rather than a couple or a few weeks.
So, yeah, made up terms for something already familiar to the reader is (again) clunky and unnecessary. Making up words does not make up for the minimal attempt that was made in world building. They had a good idea, with the rings, but it was never fully explained.
Coming back to add that I found the glossary, but it's before the first page, so Kindle doesn't (at least for me) show it when you start reading. Clicks are seconds, rotations (I think this was used once) are hours, and there is no term for week.
There are only two races: dwellers (the slaves, apparently) and the sols. Nothing to separate the two, other than the sols are apparently shiny, whereas the dwellers are dull. No backstory to that dynamic - it just simply is.
Ugh, these two must have made it their goal to write the mostly stupidly offensive (or offensively stupid) "heroine" possible. The main character, Willa, is the epitome of 'Too Stupid to Live'. And apparently, she is really clumsy and has bad luck - how do I know? Because the authors made sure to mention it on nearly every single page (I wish this were an exaggeration - it is not). That's apparently the 'curse' in "Curse of the Gods".
She's nothing more than a Mary Sue, right down to the eyes that change color depending on the eye color of the person looking at her (seriously?!), who openly admits to being stupid and having a "minuscule little mind".
Emmy, her best friend. Doesn't really appear that much in the story, so she's just kinda tacked on to make sure Willa doesn't kill herself or anyone else with her stupidity in the beginning.
The Abcurses: 5 meatheads, sorry, brothers, without distinct personalities. Seriously, more time was spent describing the various shades of green that their eyes were, throughout the entire book. They supposedly each had a distinct power, but they all just seemed to make Willa horny and even more stupid.
It pretty much boils down to watching Willa make an idiot of herself. I don't want to give away anything (there's so little of it to begin with), but she gets mixed up in something that doesn't involve her, and she manages to get herself nearly killed a few times, and then somehow bound to the meatheads... sorry, the brothers.
The only true trickery here was using decent cover art to lure people into a terrible book. I will most definitely not be reading the rest of the series. Never before have I shaken a book or Kindle in such frustration.
