Haha. I'm posting the entire first book to my series on here, so I can only hope that it's not against the rules.
Yes, we are allowed to post sneak peeks into books we have written. I did so several weeks ago and I did not get any flack from the HubPages executives. Also, I am presently following several other hubbers who are posting sneak peeks of their books.
And I must say that if a hub giving a sneak peek of a book is effectively promoted, that is nearly as good as having a full-page ad of one's book in the N.Y. Times Book Review.
But still bio and dedications will be better in the published version. Whatsoever it may be fiction or non-fiction it would definitely have readers who may be interested in your subject of writing. Go ahead and publish a hub about the subject of the book.
Well I left an excerpt The courage to heal. So we shall see.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
