Easy to read without paying too much attention, and I did't find it scary at all… Which surprised (and disappointed?) me quite a lot thinking of all the other reviews on here. It's an interesting portrait of humans and the borders of humanity, with the beautiful setting of a tiny island somewhere where it's still warm enough to survive (if you find a way to handle certain dangers). The frogs are described rather aesthetically, too. The end had a severerly melancholic touch.
