The protagonists are in addition to the right sympathetic young people, some pretty disturbed psychopaths and other not so clear to classify people, all characterizations are well integrated and understand, as far as the secondary characters.
The novel begins as a harmless classic young adult SF-history, as one of the most popular in North America apparently high school stories, but not overtightened so silly as playing movies in this area. Be told the experiences of a brother and sister and their friend from changing perspectives. The boy and the two girls (young people) act largely logical and comprehensible also according to their age. Time begins the SF novel in our presence, through this field of technology and physics so you need to worry.
The first novel begins quite slowly, he is gaining momentum, as well as complexity and later contains some pretty brutal, shocking elements. A real highlight is the cliffhanger in the short final chapters.
Despite the frequently changing perspective, you will find a quick access to the figures.
The declarations of the fictional scientific, physical background should classic SF fans a lot of joy and made me a relatively thoughtful impression.
Several topics were touched on only briefly and some complications are then but a little too predictable or constructed (the points but I can not reveal without Spoilergefahr), but these are just a few disturbing points and I'm curious how the story in the following novels further developed.
The language in this English novel is to cope well with moderate English skills.
This prelude novel reaches for me good 4 stars also because of its good dose of British humor, the successor is already on the Kindle.
