Goosebumps "Night at Terror Tower"

Last week, I finished reading the novel Goosebumps: "Night At Terror Tower". This novel was writen by R.L.Stine, he also wrote the sequence of the novels. This novel talks about a girl and her brother which from no were lost their memories. During the novel, they discover their whole past history. I thought this novel was really well written because it gives alot of suspence.
