Preorders are available for System Error for both eBook and audiobook formats. You can already obtain the paperback here, and I believe you can also rate and review the paperback--I'd really appreciate it if you did, since it is much better for a book to have a 'shield' of ratings prior to launch to prevent Amazon trolls from having a great impact. I would love any form of support you can provide, whether that's through a rating, a review, or a pre-order. Thank you.
