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.
