Allie and her two best friends, Rob and Juliet all have Xeroderma Pigmentosum, better known as XP. They are all allergic to the sun. They can only come out after dark. People with this disease do not live to be old.

Allie, Rob, and Juliet have had this all their lives. Allie's parents found out before she was even born. The trio has decided that this is not going to get them down. They do all the same thing as the average person except at night.

Their newest venture is climbing walls and jumping buildings. One night when she was climbing down a building, Allie sees what seems to be a murder. Her friends think she is nuts, but Allie knows what she saw that night. As much as Allie wants to ignore this, other strange things start occurring.

Jacquelyn Mitchard books are very intense. I have to say WHAT WE SAW AT NIGHT started out slow; I actually put it down and just picked it up again yesterday. Once I started reading WHAT WE SAW AT NIGH again, I just couldn't put it down. Mitchard talks about what these kids have to go though, just to make it though a day.

Jacquelyn Mitchard kept me guessing though the whole book. I was starting to have doubts about what Allie had seen. Was she just imaging these things or where they really happening. In parts I felt very sorry for the characters. I can't even image what someone with this disease along with their family have to go though to keep them safe from the sunlight.

WHAT WE SAW AT NIGHT is a great book, like I said it starts out slow, but you get locked into it.
