Your next novel should be about an oversensitive writer that slowly, cruelly, and methodically destroys the lives of those who have been critical. Then ask them again what they think about it.

At least they were honest. I won't speak on their harshness, I have no idea on your relationship with them and bluntness might be part of how you all interact. However, OP, don't give up. Keep writing!

What's it about?

Sniffing boot polish? Please don't tell me that's going to become to new fad. .-. Lol But good for you, OP. I'm sure your novel turned out just fine. :)

Although it is humorous to read, your friends were harsh about evaluating your work. I'm not saying that they should have lied and told you that they like it, but constructive criticism would have been a much better option. The way you put it, OP, your friends sound like insensitive assholes.

If more than one person said it then u should probably consider the possibility that it actually might suck and they weren't lying...

Well since they aren't very helpful, I would suggest looking at these things: 1) Punctuation, if you aren't good at punctuation, writing a good book will be incredibly difficult for you. 2) The first sentence. The very first sentence has to make the person interested so these are recommended: a minor sentence, a one word paragraph, onomatopoeia, a well written dramatic sentence or actions which can make the situation seem dangerous which can either be achieved by starting at the end of the book and jumping back in time, starting off with a chase scene or making a safe situation appear dangerous and reveal it isn't. Not recommended: A name as the first word, a dull sentence with boring day to day actions only, description of the setting or character. 3) The amount of description. Several people make the mistake of giving too much description which can honestly turn a brilliant book into mind-numbing drivel which I have seen in multiple books sadly. You don't need to describe every single location nearby in excruciating detail, you only need to describe, in a fair quantity of detail, the important locations and give vague descriptions of unimportant locations they will only be at for a few pages. 4) Characters. Mixing too many characters into one story will make it boring AND confusing for people so you have to limit the main characters to 6 or below. Also, supporting characters shouldn't just disappear into the abyss, use the ones you establish, don't bring in 500. I have seen books make this mistake and it has made me extremely confused because I don't remember who R is when they only appeared in page 213 and then it focuses on S, S2, S3, T, R2, Q, R3, D, D2 and L before suddenly bringing R back in page 402. 5) Word choice. Look up synonyms of words you know that you use too frequently because a varied vocabulary is required to make a good book. 6) Genre. Don't try to cram all genres into one book, you need to pick one and focus on it, some others will get mixed in as the book progresses depending on how you write it but you can't try to mix in everything. 7) Consistency. You can't suddenly conjure up a dragon in a book that states there is no magic and no dragons 5 pages ago.

Well that's rude! Ask them to not be so blunt next time.

Nobody told me boot polish gets you high... maybe I'll have to go and polish my boots.

Well I guess you can't be to mad at them for not lying to you, although they were to blunt they could of said it in a better way. Perhaps you should re-write your book and show it to your friends again.
