Are you going to read the first book of the third TC trilogy?
As for the HDM trilogy, they evoke a strong feeling in me. A good thing in the norm for a book, but its not the content and subject matter I feel strongly about it is the author and the books themselves. They're slow, the characters are badly formed, the main character in the first book is very cold, you feel like you're constantly being preached at, though the author hates the church and really doesn't hold back in saying so through the medium of his books... By the end of it the plot twists are so stupid you don't even care about what happens any more. I found myself plodding through them just to make sure I never return to waste my time on them again - if I don't finish a book there's always that doubt that they finish strongly. These ones really, really, really don't.
The level of English used is poor. At least, on the whole it is OK but on every other page there's a phrase that jumps out at you as childish. It ruins the flow of the books which isn't good to start with.
The first is an OK read, the second far less so, the third is easily the worst book I've read for 5 years. Fine for preteens and early teens, nothing more. Thats from someone that enjoys the Harry Potter books.
