This isn’t a beach. It’s Lake Lyn. The Lake Lyn?
Also there's this thing with the sea, that has been a huge part. Emma being scared of it, because of her parents and Jules (and the other Blackthorn kids?) loving it, because it reminds them of home and sea demons and stuff being present. Lastly, there's Thule, which was mentioned a couple times in the book. The poem in the beginning of course, but also one of the Seven says something about it..? Thoughts about all this? (pt3)
