It’s that time of year: November is “Nanowrimo” or National Novel Writing Month, when ambitious authors take the challenge to write the first draft of a novel from start to finish in a month. While gearing up for the challenge, writers are looking for advice, techniques, and resources.

And boy do we have a toolkit for you! I’ve curated an impressive collection of  a dozen books on writing that will be inspirational, helpful, maybe even provocative. You can get all of the books for as little as $15, and a portion of the proceeds goes directly to benefit the Challenger Learning Center for Space Science Education.

In this bundle, you’ll get titles with basic nuts-and-bolts advice on writing, including How to Write a Novelby Simon Haynes, Story Pitchby Scott King, The How-To Structure Workbook for Trilogies, Series, and Parallel Worldsby C. Michelle Jeffries, Writing As a Team Sport on collaboration by Kevin J. Anderson and Rebecca Moesta (we included a partial sneak-preview of this book in last year’s bundle, and this version is greatly expanded), and How to Polish Your Manuscript into a Rock-Solid Bookby Andrea Pearson.

We’ve included inspirational and motivational titles to get your book done, You Must Write: Success Through Heinlein’s Rulesby Kevin McLaughlin, Pulp Speed for the Professional Writer by Blaze Ward, and How to Write a Novel in Ten Daysby Dean Wesley Smith (and, yes, he does that…regularly).

And for those of you thinking about the big picture, we have important career advice with The Secrets of Successby Kristine Kathryn Rusch, Become a Successful Indie Authorby Craig Martelle, and The Healthy Writerby Joanna Penn. For those of you interested in the whole process of bundling, we include the storybundle exclusive, Bundle Up!by Jamie J. Ferguson.

In short—you need these books!

The Nanowrimo Writing Tools bundle runs from October 3 through November 30, so you can pick it up at any point during the course of writing your novel. (But it’s best to start building up your skills right away.)
