SOLVED. YA Thriller/ Horror fiction about children in a swamp. Read in 2012. [s]

[Austin]

So back in high school I read a horror novel about a couple of small children who were dropped of at their grandmothers house in England . Their grandmother lived in a swamp in a rickety old mansion. One of the first things their grandmother told them is don't go into the swamp when there's a high tide. Eventually they started hearing weird noises at night and strange things around the yard. There ended up being a weird monster that we tied to the water in the swamp and the house was only protected when the tide was down. I would have read the novel in I believe 2012. I was so hooked on it but I fail to remember when I stopped reading it. It may have been because it actually scared me to be honest.

Also yes Becca that was quite a while ago it came to mind again so I figured I'd post again. I forgot actually about my initial inquiry.
