Authonomy.com — readers rating MS’s for Harper Collins UK.
In other words, if you participate, you are serving the function of unpaid MS readers for Harper Collins UK. Why bother? It’s like voting on the books you want to see published, instead of relying on someone else to make that decision for you.
It’s also a hell of an education to see how many writers are out there, and how good they are — and they’re still not published. Reality is a good teacher. If you’re serious about getting published in the future, Authonomy will help.
You can put your own MS’s up for consideration at Authonomy. The five highest-rated MS’s each month get reviewed by real Harper Collins UK editors, for possible publication.
