Please can someone help me, I'm at my wits end trying to remember a books title. The story starts with either one or a group of soldiers appearing from some where else. The main character is a female who lives in a house buit on the water of a lake, which is down a large crater. There are divers for this lake but it is forbidden for anyone to go into in when it is mirror still. However a "simpleton" falls in and disapears. The story follows the female and friends who try to find out what is going on.
I read this book a good few years ago (I even can't remember how long ago it was) please can someone help tia!! xx
I've looked a bit and still can't find anything. This is the closest I got, but it doesn't seem quite right:
Can you provide any other details?
I know you read it a few years ago, but any idea whether it was new at the time?
Any idea what the cover looked like?
Do you remember where you originally heard about it?
Any other odd character names or details that could help?
Any other standout, strange plot details, even if they're small?
