I can't say it was bad, but the writing wants a little bit of improvement if it's to be classed as average. The good part is that it reads OK and you can get through it pretty fast, but the writing is simplistic, and I wouldn't say that the world-building or characterization lifts it up.
The characters are rather flat, and there isn't much to them outside of what they're apparently doing in relation to each other, which can be fine in quick romances, but not if you're aiming to leave a lasting impression.
Pearl is a special cookie, an archivist with some apparent interest in books not that she does much which includes them aside from the mandatory research she needs once she discovers she's now a special cookie, who hasn't got much faith in herself, and seems to have a whole lot of baggage, an extended family she isn't in contact with, a best friend whose friendship doesn't need maintenance, and a very handsome man for a mate who loves her despite having no clue about the adult she's become.
Rylan isn't much better himself, being distinguished by *knowing* that he's got a special well of power inside him, and being more alpha than all the alphas (in the world, or just this tiny community they have here? No clue, the world building needs work), and apparently is a better dude than his cardboard bad guy cousin.
I'm picking on it, because it could easily have been better with a bit more work and attention, but I'm assuming the author was on a schedule, so it is what it is. It's not consuming reading, and it's not incredibly memorable, but it reads easily so it has it's place when you don't want to engage your brain too much.
N.B. Ends on a cliffhanger, so you have to read book two to figure out where it was headed.
