Overall, I like this. There are some things I didn't understand like how he is able to read Morgan's mind and she his, but Lilly seems to not have that gift. However, this is chapter two and this all could have been explained in chapter one, and if it wasn't it needs to be. You have some great description in here. When you describe Lilly looking at him, you describe her as giving him a "death glare" that is great. In the very beginning he is coming awake slower than eyes being pried open, so I would use something slower like eyes fluttering open, or eyes opening halfway or something denoting a slower, more subtle awakening. When I think of eyes being pried open I think of a sudden alertness due to something alarming. He is certainly not alarmed here. Now, Morgan is fifteen years old? And she is the only employee of this club? And she seems to know everything about this kingdom? And she seems to set the rules too? That is a lot to digest and to have set out and have it only be Chapter two. Then this monster comes and it is clearly identified as a he...but when it falls it is only a head...how can only a head be gender specific?

There is a whole lot here about boundaries that does not really pertain to your characters here. In which case it would be called filler. Until it pertains to them and they need to know it. In other words they are going to be going outside alone and they might be in danger and they really need to know what these boundaries mean, what is the point in quickly running through these boundaries that they aren't going to remember and likely neither is your reader. It only serves to confuse the reader and make them have to read several times to figure out what is what and why this is being stated at this point and time. If there is a reason clearly let the reader and the character know that up front.

Keep Writing.
