I wrote this book over the past 6 months to share the UX design and prototyping process that I've used to design several startup products.
Since it's my birthday, I'm making this kindle book free on Amazon today.
Here's a direct link to the book on Amazon: http://www.amazon.com/dp/B00X8U2BCY
You can read it on any kindle device or kindle app on mobile/tablet
Hope you enjoy it!
