Available until Sep 1st, 2018: the pre-publication version for half the price ($5)!

After a successful PayPal transaction, you receive a download link to the pdf file. For ePub and mobi (Kindle) formats, click here. In the pdf file, each page is visibly watermarked with your name. The ePub and mobi files have no visible watermarks. Instead, they have a digital fingerprint that can be traced back to the purchase. In case of any problems contact me at riku@thebackupcolony.org

NOTE FOR MAC USERS: There have been a couple of instances where the return to the download page from PayPal has failed. The common nominator seems to be a Mac + either Safari or Firefox browser. The problem is under examination by the service provider. Meanwhile, I will fix the missing orders by “hand” so that you will get an email with the download links. Sorry for the inconvenience; hopefully, the issue will be sorted out soon.
