I'd have to agree with much of what LTU is saying, although I have to dissent on the issue of cliche.
Yes, much of this is an oft-used formula, but while I was reading it, I didn't even notice. My second read-through was the first sign I saw of it, and that may be because the second read is where I put on my critiquing glasses. However, I feel you made the cliche work for you, rather than against. A small village, not many visitors, young girl... I knew something would be brewing, something was going to come kick in the door and shatter the idyllic little hamlet. That inevitability worked with the pacing - which I thought was handled very well - and although it didn't quite shock me when it happened, up until the moment it did it had me wondering
when. In a good way. Sometimes the scene everyone expects is the one you want to use. Preferably, though, you'll hit us with something completely unexpected in the next few chapters.
The catfish thing was hilarious, and I enjoyed the voice and prose (again, must voice agreement with LTU on the switches in personality. Was a bit odd in some spots.)
One issue I did have is with a few of the descriptions. Several of them felt out of place - the one referring to the cobblestones stands out to me most. Reading it makes me feel as if Rosalin just stopped walking and stared at the cobbles, then continued on after analyzing them for a few moments. I think it would feel significantly stronger if the description was woven more tightly with the narrative - perhaps Rosalin almost slipping on the stones to show that they're wet and slightly hazardous, or nearly being splashed by the mud. That said, this line stood out beautifully:
"The stones were solitary islands in the muck, threatened to wash away."
The imagery there felt quite strong, doing more to help me visualize the scene than the pure lines of description that came before it.
Other than that, the only other issues I can think of are purely technical, and some likely the result of my own little borderline obsessive-compulsive tendencies. Commas where periods or em dashes felt more appropriate, some jarring repetitiveness in word choice that threatened to snap me out of the story just as I was immersing myself.
