There's a pretty good story here overall, but the book itself obviously wasn't proofread very well. There are many spelling mistakes (yes, taking UK spelling into account), missing words, wordsjoinedtogetherlikethis and a huge number of homonym transposition errors (peer/pier etc.). I hope the author does themselves a favour and has some good proofing done next time.
BTW, to the people below who obviously have no etiquette, please don't spoil the endings of books for people.
Solid concept and certainly interesting enough to keep you reading. Sadly, as with some other titles on here, it hasn't been properly proofread and there are many grammar errors and missing words. I'm also assuming from the rather abrupt ending that there is a sequel.
