PENUMBRA PUBLISHING IS CLOSED TO ALL SUBMISSIONS.
We thank you for your interest in Penumbra Publishing, but as of January 2016, we are no longer accepting submissions. If you have sent a submission or query, were promised a review of your manuscript, or had a publishing contract, please accept our apologies, as we are no longer publishing new authors' books. We encourage you to find other publishing venues and don't give up. In the past seven years we've helped over thirty authors become published, and when a door closes, a window opens. Keep searching, you WILL find your window of opportunity.
PLEASE DO NOT SEND US SUBMISSIONS OR QUERIES.
