It was technically available last Friday if you wanted to order the paperback. But the pre-order period is now complete and you can read the full e-book starting today!
Personally, I prefer physical books over e-books. It obviously costs a little bit more, but still. It just feels better to read from an actual book. Plus, I’m very proud of the work I did in putting the physical book together, even if the author’s commission is less for the paperback. I’m happy with Hooky, too, but I learned a lot and I think I put together a better looking product with On His Orders.
