I'm in the midst of edits on two books - along with finishing up another for submission - so I'm time crunched at the moment but I wanted to give a brief shoutout to my critique partners (or CPs.) They've helped me so much. Taryn has been there from the beginning and has saved me numerous times, while some of the others are newer but still so helpful. It's so nice to have another couple sets of eyes to go over your story before you submit. And believe me, editors appreciate authors who have others give their manuscripts a read before they hit send! Even the most seasoned author is too close to their story to see all the potential holes. True, sometimes it's just not possible to have someone take a look before you sub, especially once you're a published author with close deadlines. But whenever possible, it's a good idea. They'll see things you never thought of...and if you're lucky, help you make your book the strongest it can be before it has to compete with all the other books in your editor's inbox.
Do you use CPs or beta readers? Have they helped you along the way?
